Infleqtion Partners with Japan's Science Agency, Eyeing a Quantum Future by 2050 - HPCwire

Harvard researchers have realized a key milestone in the quest for stable, scalable quantum computing, an ultra-high-speed technology that will enable game-changing advances in a variety of fields, including medicine, science, and finance.

The team, led by Mikhail Lukin, the Joshua and Beth Friedman University Professor in physics and co-director of the Harvard Quantum Initiative, has created the first programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations, a vast improvement over prior efforts.

Published in Nature, the work was performed in collaboration with Markus Greiner, the George Vasmer Leverett Professor of Physics; colleagues from MIT; and QuEra Computing, a Boston company founded on technology from Harvard labs.

The system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.

"I think this is one of the moments in which it is clear that something very special is coming"

Mikhail Lukin, Joshua and Beth Friedman University Professor in Physics

Lukin described the achievement as a possible inflection point akin to the early days in the field of artificial intelligence: the ideas of quantum error correction and fault tolerance, long theorized, are starting to bear fruit.

I think this is one of the moments in which it is clear that something very special is coming, Lukin said. Although there are still challenges ahead, we expect that this new advance will greatly accelerate the progress toward large-scale, useful quantum computers.

Denise Caldwell of the National Science Foundation agrees.

"The team has not only accelerated the development of quantum information processing by using neutral atoms, but opened a new door to explorations of large-scale logical qubit devices, which could enable transformative benefits for science and society as a whole."

Caldwell, acting assistant director of the Mathematical and Physical Sciences Directorate

This breakthrough is a tour de force of quantum engineering and design, said Caldwell, acting assistant director of the Mathematical and Physical Sciences Directorate, which supported the research through NSFs Physics Frontiers Centers and Quantum Leap Challenge Institutes programs. The team has not only accelerated the development of quantum information processing by using neutral atoms, but opened a new door to explorations of large-scale logical qubit devices, which could enable transformative benefits for science and society as a whole.

Its been a long, complex path.

In quantum computing, a quantum bit or qubit is one unit of information, just like a binary bit in classical computing. For more than two decades, physicists and engineers have shown the world that quantum computing is, in principle, possible by manipulating quantum particles be they atoms, ions, or photons to create physical qubits.

But successfully exploiting the weirdness of quantum mechanics for computation is more complicated than simply amassing a large-enough number of qubits, which are inherently unstable and prone to collapse out of their quantum states.

The real coins of the realm are so-called logical qubits: bundles of redundant, error-corrected physical qubits, which can store information for use in a quantum algorithm. Creating logical qubits as controllable units like classical bits has been a fundamental obstacle for the field, and its generally accepted that until quantum computers can run reliably on logical qubits, the technology cant really take off.

To date, the best computing systems have demonstrated one or two logical qubits, and one quantum gate operation akin to just one unit of code between them.

The Harvard teams breakthrough builds on several years of work on a quantum computing architecture known as a neutral atom array, pioneered in Lukins lab. It is now being commercialized by QuEra, which recently entered into a licensing agreement with Harvards Office of Technology Development for a patent portfolio based on innovations developed by Lukins group.

The key component of the system is a block of ultra-cold, suspended rubidium atoms, in which the atoms the systems physical qubits can move about and be connected into pairs or entangled mid-computation.

Entangled pairs of atoms form gates, which are units of computing power. Previously, the team had demonstrated low error rates in their entangling operations, proving the reliability of their neutral atom array system.

With their logical quantum processor, the researchers now demonstrate parallel, multiplexed control of an entire patch of logical qubits, using lasers. This result is more efficient and scalable than having to control individual physical qubits.

We are trying to mark a transition in the field, toward starting to test algorithms with error-corrected qubits instead of physical ones, and enabling a path toward larger devices, said paper first author Dolev Bluvstein, a Griffin School of Arts and Sciences Ph.D. student in Lukins lab.

The team will continue to work toward demonstrating more types of operations on their 48 logical qubits and to configure their system to run continuously, as opposed to manual cycling as it does now.

The work was supported by the Defense Advanced Research Projects Agency through the Optimization with Noisy Intermediate-Scale Quantum devices program; the Center for Ultracold Atoms, a National Science Foundation Physics Frontiers Center; the Army Research Office; the joint Quantum Institute/NIST; and QuEra Computing.

Supplementary Video 1 is Atom video for coherent atom motions used in this work. These videos depict the coherent atom motions employed for the quantum circuits realized in these experiments. To perform parallel entangling gates, indicated by red ovals, the relevant pairs of atoms are brought within close vicinity (~2 m). Supplementary Video 1: Fault-tolerant 4-qubit GHZ state using d = 3 color codes (Fig. 3). Ten color codes, arranged in two rows of five codes with 7 physical qubits per code, are encoded in parallel and the bottom row of five logical qubits are used as ancillas in the transversal CNOT and are then moved to the storage zone. The leftmost four computation logical qubits are then used to prepare a GHZ state.

Suppressing errors is the central challenge for useful quantum computing (1), requiring quantum error correction (2,3,4,5,6) for large-scale processing. However, the overhead in the realization of error-corrected logical qubits, where information is encoded across many physical qubits for redundancy (2,3,4) poses significant challenges to large-scale logical quantum computing. Here we report the realization of a programmable quantum processor based on encoded logical qubits operating with up to 280 physical qubits. Utilizing logical-level control and a zoned architecture in reconfigurable neutral atom arrays (7), our system combines high two-qubit gate fidelities (8), arbitrary connectivity (7,9), as well as fully programmable single-qubit rotations and mid-circuit readout (10,11,12,13,14,15).

Operating this logical processor with various types of encodings, we demonstrate improvement of a two-qubit logic gate by scaling surface code6 distance from d=3 to d=7, preparation of color code qubits with break-even fidelities5, fault-tolerant creation of logical GHZ states and feedforward entanglement teleportation, as well as operation of 40 color code qubits. Finally, using three-dimensional [[8,3,2]] code blocks (16,17) we realize computationally complex sampling circuits (18) with up to 48 logical qubits entangled with hypercube connectivity (19) with 228 logical two-qubit gates and 48 logical CCZ gates (20). We find that this logical encoding substantially improves algorithmic performance with error detection, outperforming physical qubit fidelities at both cross-entropy benchmarking and quantum simulations of fast scrambling (21,22). These results herald the advent of early error-corrected quantum computation and chart a path toward large-scale logical processors.

Many observers now think its unlikely the National Quantum Initiative Act of 2018 will actually get reauthorized this year. Its up for a second five-year commitment and there is finally a bill in congress (H.R.6213 National Quantum Initiative Reauthorization Act). That said, the legislative logjam is such that reauthorization may have to wait.

One long-time observer noted, These authorization bills are interesting and nice, but are really not essential. It is the appropriation bills and the policy directions they contain that really matter. As the saying goes, Follow the money. The good news is that each Congress lasts for two years. That is why we are only on the 118th Congress. So given that we have another year to go, I would say there is a decent chance this will be acted on in the 118th Congress. However, the bad news is that if it isnt, the 119th Congress that starts in January of 2025 will start fresh, so the reauthorization bill has to be reintroduced.

In the follow the money line of thought, a new National Quantum Initiative Supplement to the Presidents FY 2024 Budget was just released (Dec 1) and may provide directional guidance, at least to the Presidents spending plans. The new report, prepared by the Subcommittee on Quantum Information Science Committee of the Science of The National Science & Technology Council, also provides updated background on NQIAs mission as well as spotlighting a few accomplishments so far.

Think of it as reasonably quick reading for the Holiday season for quantum community watchers. For the brave reader, the report has an eye chart figure at the end attempting to summarize key timeline and implementation steps for NQIA (also included at end of this brief article).

As seen below, budgets ramped up quickly more than doubling from 2019 to 2022 (slide below). The report doesnt have precise tables but it looks like on the order of $3plus billion were spent on QIS in those years. The report writers suggest the budget will close down in 2023 and the 2024 request is for less than $1 billion.

As noted in the proposed budget, Overall federal budgets for U.S. QIS R&D activities [are] aggregated across several agencies including NIST, NSF, DOE, DOD, the Department of Homeland Security (DHS), and the National Aeronautics and Space Administration (NASA). Much of the growth in QIS R&D budgets is for NQI activities such as the establishment of a quantum consortium [The Quantum Economic Development Consortium] by NIST, the NSF Quantum Leap Challenge Institutes (QLCIs), the DOE National QIS Research Centers, and the coordination and strengthening of core QIS programs across many agencies.

Its good to remember that NQI work encompasses a good deal more than quantum computing. Here the lest of principal component areas from the report along with that budget breakdown and the breakdown by federal agency spending (slides below):

Much of the report covers familiar ground but there is a dedicated section highlighting accomplishments; its broken down by the agency doing the work and is worth scanning. Shown below is a bulleted list of representative advances by NIST included in the report. There are somewhat similar lists of advances by other agencies. There are also a few sidebars summarizing technical advances in areas ranging from superconducting qubit development, to erasure qubits and mid-circuit measurements, and to testing quantum sensors used in pacific rim.

Bulleted list of NIST-led advances from the report:

All in all, its a report, but a quickly navigable report for those broadly familiar with the quantum information sciences. Lastly, shown below is the eye-chart depicting NQI implementation to date.
