Quantum computing is an incredibly promising innovation but it also jeopardizes current data protection methods. This emerging field requires an urgent collaborative response to safeguard privacy.

Quantum computers leverage quantum mechanics principles like superposition and entanglement to perform calculations exponentially faster than regular machines for certain tasks.

Through parallel computation on a massive scale, they hold huge promise for challenges from chemical simulations to machine learning.

Global tech giants like IBM and emerging startups have pioneered early but extremely powerful prototypes. However, unlocking the immense potential of these machines also necessitates upgrading crucial cybersecurity foundations built in a pre-quantum age.

Encryption protocols most of the digital world relies on remain dangerously exposed. As quantum hardware continues rapid advances, failure to future-proof security risks compromising privacy on an unprecedented scale.

A world with advanced quantum computers puts all current encrypted data at risk of interception and misuse. No existing encryption method would remain reliably secure.

Pretty much all sensitive data transmitted online - from financial records to government secrets and personal emails - depends on mathematical encryption techniques to prevent interception.

The most common public key encryption schemes used today like RSA, ECC and Diffie-Hellman base their security on the extreme difficulty for regular computers to factor very large prime numbers. This allows easy encryption by multiplying two large primes but makes decryption essentially impossible through brute computational force.

However, quantum computers can run algorithms like Shor's to quickly factor these large numbers and break the encryption. Where even the most advanced supercomputer would take millennia, a powerful enough quantum computer could unravel the security on such data in minutes.

The Quantum Computing Threat to Encryption and Cybersecurity - Medium

Quantum computing looks like it will be a tremendous game changer for society because it provides massive operational power advantages over classical computers. In fact, quantum computers can carry out calculations in minutes vs. todays supercomputers, which take at least several days or years to perform. Reportedly, the technology can significantly improve many sectors, including manufacturing, where it will enable more accurate and realistic prototyping and testing and drug research where its ability to foster a superior and more precise understanding of molecular structure will be transformative.

Among the other fields that quantum computing could significantly improve are artificial intelligence (AI), financial modeling and cybersecurity. Despite the vast potential, the value of most quantum computing stocks is quite low, allowing patient investors to generate huge profits as the technology matures. Such investors should consider snapping up these three quantum computing stocks, which appear to be tremendously undervalued.

Rigetti Computing (NASDAQ:RGTI) develops quantum computers and superconducting quantum processors, along with a quantum-computing-as-a-service platform adaptable for various cloud setups, another InvestorPlace columnist, Matthew Farley, noted.

Impressively, the company was founded by Chad Rigetti, a physicist and computer scientistwho developed quantum computing for IBM (NYSE:IBM) before launching his own company in 2013. Although Rigetti left his namesake firm earlier this year, he obviously left a tremendous imprint on it.

Rigetti Computing seems to be making significant progress, as it sold its first quantum processing unit in the second quarter, leading research firm Benchmark to predict the company will make similar, additional deals going forward. Indeed, RGTI delivered another QPU last quarter.

Praising the ease of use of RGTIs offerings, Benchmark raised its rating on the shares to Buy from Hold and placed a $4 price target on the name versus its current price of just over $1.

Another big achievement by the company was its attainment of a five-year deal to provide theAir Force Research Labwith the ability to create customized quantum systems.

The market capitalization of RGTI is just $150 million, a level that vastly undervalues the companys long-term potential.

D-Wave Quantum (NYSE:QBTS) has reportedly created the first quantum computer ready for industrial applications, giving it an important, first-mover advantage in the space.

And somewhat validating D-Wave and its technology, the company has several very impressive customers, including Volkswagen (OTCMKTS:VWAGY), Toyota (NYSE:TM), Lockheed Martin (NYSE:LMT) and Japanese auto parts maker Denso (OTCMKTS:DNZOY).

Moreover, in the first three quarters of the year, D-Waves bookings jumped 125% year-over-year to $8.4 million, while its Average Deal Size per booking increased by 172% for commercial customers and 178% for all customers when comparing the most recent four quarters with the immediately preceding four quarters.

Given D-Waves rapid growth and huge potential, its $134 million market capitalization is clearly quite low, making it one of the best quantum computing stocks to buy.

Arqit Quantum (NASDAQ:ARQQ) developed a quantum encryption system thats unbreakable and can, relatively cheaply, protect every edge device and cloud machine in the world, according to Seeking Alpha columnist Jay Capital.

He and many other commentators predicted that quantum computers will be able to hack Public Key Infrastructure (PKI) systems over the longer term. PKI is currently the most popular means of protecting data. As a result, new methods of protecting data will have to be found, and ARQQ appears to have a first-mover advantage in that area.

Among ARQQs customers are the U.K. Government [and] the European Space Agency, along with BT Group, a huge British telecom company and Sumitomo (OTCMKTS:SSUMY), a Japanese conglomerate.

Among those testing the product are Verizon (NYSE:VZ), BP (NYSE:BP) and Northrup Grumman (NYSE:NOC).

Arqit looks poised to become a gigantic cybersecurity company, and almost none of that potential is reflected in its current market capitalization of $82 million.

Announced at its annual IBM Quantum Summit in New York, IBM has unveiled its IBM Quantum Heron, the first in a new series of quantum processors engineered to deliver high performance metrics.

IBM also debuted the IBM Quantum System Two, the companys first modular computer and cornerstone of IBMs quantum-centric supercomputing architecture. Located in Yorktown Heights, New York, the first IBM Quantum System Two has begun operations with three IBM Heron processors and supporting control electronics.

Dario Gil, IBM SVP and director of research, said: We are firmly within the era in which quantum computers are being used as a tool to explore new frontiers of science.

As we continue to advance how quantum systems can scale and deliver value through modular architectures, we will further increase the quality of a utility-scale quantum technology stack and put it into the hands of our users and partners who will push the boundaries of more complex problems.

Having demonstrated its 127-qubit IBM Quantum Eagle earlier this year, IBM Quantum systems now serve as a scientific tool to explore utility-scale classes of problems in chemistry, physics and more.

Since the demonstration, leading researchers, scientists and engineers from organizations across the globe have expanded demonstrations of utility-scale quantum computing to confirm its value in exploring uncharted computational territory. This includes experiments running on the IBM Quantum Heron 133-processor, which the company is now making available for users via the cloud.

IBM Quantum System Two combines scalable cryogenic infrastructure and classical runtime servers with modular qubit control electronics. This architecture combines quantum communication and computation, assisted by classical computing resources and leverages a middleware layer to integrate quantum and classical workflows.

As part of IBMs expanded ten-year quantum development roadmap, the company plans for this system to house IBMs future generations of quantum processors. Additionally, IBM has also unveiled plans for a new generation of its software stack and has announced Qiskit Patterns which aim to democratize quantum computing development.

Qiskit Patterns will serve as a mechanism to allow quantum developers to easily create code. With Qiskit Patterns, combined with Quantum Serverless, users can build, deploy and execute workflows integrating classical and quantum computation in different environments, such as cloud or on-prem scenarios.

Jay Gambetta, vice president and IBM fellow at IBM, said: GenAI and quantum computing are both reaching an inflection point, presenting us with the opportunity to use the trusted foundation model framework of watsonx to simplify how quantum algorithms can be built for utility-scale exploration.

This is a significant step towards broadening how quantum computing can be accessed and put in the hands of users as an instrument for scientific exploration.
