Mitsubishi Electric has invested in OptQC through its ME Innovation Fund, backing a Japanese startup developing optical quantum computer hardware designed for large-scale systems. OptQC originated from the University of Tokyo and was established around technologies developed by the university’s Furusawa Laboratory, a research group focused on optical quantum computing. Optical quantum computing uses photons as the basis for quantum information processing. For Mitsubishi Electric, the investment provides an opportunity to gain earlier visibility into OptQC’s technology development and the emerging commercial market around optical quantum computing. Mitsubishi Electric said it aims to use the relationship to strengthen its position in quantum computing while developing potential new businesses around the technology.
Building or Buying Access to Quantum Computing
Organizations around the world now have access to quantum computing but almost all of them simply rent time on someone else’s machine, typically through a cloud account with one of a handful of hardware providers. In February 2026, my team at the Technology Innovation Institute’s Quantum Research Centre opened cloud access to superconducting quantum processing units (QPUs), including QPUs we designed and fabricated in-house at our Quantum Computing Hardware Lab in Abu Dhabi. This is part of why a growing number of governments now treat quantum hardware capability as a strategic asset, alongside the more familiar conversation about quantum-safe cryptography. What has changed is more basic: the set of institutions capable of building and operating real quantum hardware, however modest in scale, at all, is no longer limited to the handful of companies that dominate the headlines. The next meaningful milestone in quantum computing may not be a new qubit record.

Quantum Computers Need 100,000-Fold Performance Gain For Scientific Utility, Study Finds
The study estimates that current quantum computing capability must increase about 100,000-fold to reach the scientific workloads examined. The new benchmark also indicates that future quantum computers will need a significant performance boost — in the 100,000-fold range — to tackle high-value scientific problems. The Quantum Universal Operations Performance System, or QUOPS, measures the largest useful-sized test circuit a quantum computer can run above a set accuracy threshold. The second measurement, represented by the Greek letter omega, records the effective number of quantum operations completed per second at that point. Quantinuum said QUOPS is not intended to replace component measurements, application-specific tests or benchmarks for quantum systems linked to high-performance computers.
What if ordinary light could behave like a quantum machine
Instead of starting with fragile quantum sources, they begin with bright, classical light, the kind produced by everyday lasers, and use clever photon-counting techniques to reveal hidden quantum behavior inside it. Their breakthrough, published in Advanced Science, shows how ordinary light can be harnessed to perform robust quantum information processing at room temperature. Bright classical light contains vast numbers of photons, but the number reaching a detector fluctuates naturally from one measurement to the next. Each event corresponded to a different multiphoton quantum system hidden within the classical light field. Instead of fragile, expensive setups, researchers may build robust platforms that exploit the quantum behavior already lurking in ordinary light.

Which Bitcoin Wallets Are at Risk From Quantum Computers? 6.9 Million BTC Have Exposed Keys
Quick Read Google Quantum AI's March 2026 paper found 6.9 million Bitcoin in addresses with publicly visible keys, leaving them exposed to offline quantum attacks. Taproot addresses expose public keys by design, and any P2PKH address spent from even once permanently publishes its full public key on-chain. About 1.7 million Bitcoin in lost Satoshi-era keys, worth over $100 billion, cannot migrate to quantum-safe addresses because the private keys no longer exist. Every standard Ethereum account publishes its public key the first time it signs a transaction, and most active balances already have. 1.7 Million Bitcoin Locked in Keys Nobody Can Move Coinbase's Independent Advisory Board on Quantum estimates about 1.7 million Bitcoin across roughly 20,000 early P2PK keys are Satoshi-era or otherwise lost.

NEC spent decades developing quantum hardware, but it's time to leave
Its researchers produced the earliest known solid-state qubit, a milestone still referenced widely across the quantum computing field. Unlike NEC, IBM remained committed to quantum hardware and grew into a leading global developer of quantum computing systems overall. That contrast makes NEC's exit relatively rare among the original corporate pioneers of quantum computing hardware development. NEC has not formally described the move as a complete withdrawal from quantum computing research. Quantum computing hardware remains a notably costly pursuit, and returns on investment can take many additional years to materialize fully.
Tiny sound waves could help solve a major quantum computing problem
It may also help enable hybrid quantum systems that combine several different kinds of quantum bits, or qubits. Using Sound to Carry Quantum Information One promising approach to quantum networking uses the spin of an electron, associated with impurity in diamond, to store quantum information. The Challenge of Preserving Quantum Memory Using phonons, however, creates a major difficulty: protecting quantum memory. They could transport quantum information between different parts of a network while simultaneously helping protect that information from environmental noise. The result demonstrates that continuous-wave mechanical noise suppression can extend quantum coherence in real devices, suggesting that microscopic sound waves could become an important tool for building more reliable and compact quantum systems.
Quantum computing takes aim at AI
In some cases, quantum computers are already being used alongside AI to significantly improve results, notes Murray Thom, vice president of quantum business innovation at quantum provider D-Wave Systems. But operators of AI systems need to think creatively about how to use quantum computing alongside AI to get the full benefits, he adds. IT leaders must envision future AI workloads to find a place for quantum AI, he suggests. “Quantum computers could eventually accelerate some AI workloads, but I would not expect them to broadly replace GPUs,” he adds. “Quantum computers still need major advances in error correction, and any benefits will probably be limited to specific subroutines of larger AI workloads.”
Quantum Computer Recreates Particle Collisions That Turn Energy Into Matter

Ethereum and Quantum Computers: Are Your ETH Affected?
On September 7, 2026, the Ethereum Foundation announced that Ethereum L1 should become quantum-resistant by December 2029. The attack in question is called Shor's algorithm: a quantum method that derives the matching private key from a known public key. Why the public key on Ethereum is almost always exposed Here is the point at which most coverage passes your actual question by. The quantum risk does not attach to the coin; it attaches to whether the public key of an address is known. Checking Ethereum's quantum risk: what to take away Stay calm and sell nothing.
