New Hybrid Quantum Monte Carlo Algorithm
Researchers Xiaosi Xu and Ying Li have developed a “quantum-assisted” Monte Carlo method that uses a small quantum processor to boost the accuracy of classical simulations. The breakthrough, published in Quantum in 2023, addresses the notorious sign problem in quantum Monte Carlo calculations – a key issue that causes explosive uncertainty in simulations of electrons and other fermions. By incorporating…

Intel’s Tunnel Falls: 24,000 Quantum Chips Per Wafer and the Manufacturing Argument Made Real
22 Jun 2023 - Every conversation about silicon spin qubits eventually arrives at the same claim: because these qubits are essentially single-electron transistors, they can be manufactured using the same processes that produce billions of classical transistors every year. The implication is staggering — a scalable quantum computer rolled off a semiconductor production line, not hand-assembled in a physics lab.…

Google Claims Breakthrough in Quantum Error Correction
Feb 2023 – Quantum computers hold the promise of tackling problems beyond the reach of classical machines, but they are notoriously fragile. Even tiny disturbances can introduce errors into quantum computations. To build a fault-tolerant quantum computer – one that can reliably run long computations – scientists have to keep these errors in check. Google’s Quantum AI team just reported…

Scientists Achieve Entanglement Between Two Light Sources
Researchers from the University of Copenhagen and Ruhr University Bochum have made a significant breakthrough in quantum technology by achieving controlled interaction between two quantum light sources, or quantum emitters, embedded in a nanophotonic waveguide. This development, reported in Science, is a foundational step toward building scalable quantum computers and enhancing quantum communication systems. In simple terms, quantum emitters are…

IBM Osprey: A 433-Qubit Quantum Leap
IBM has announced Osprey, a superconducting quantum processor with a record-breaking 433 qubits – by far the largest of its kind as of its 2022 debut. Revealed at the IBM Quantum Summit in November 2022, Osprey more than triples the qubit count of IBM’s previous 127-qubit Eagle chip. IBM says this new processor “brings us a step closer to the…

Silicon’s First Attempts at Self-Repair: Phase-Flip Error Correction Demonstrated in Semiconductor Spin Qubits
25 Aug 2022 - Seven months ago, three teams simultaneously proved that silicon spin qubits could operate above the fault-tolerance threshold — the quality of individual gates good enough, in principle, for error correction to work. That was the prerequisite. Now comes the thing itself. Two independent groups have demonstrated quantum error correction in semiconductor spin qubits for the first…

Three Labs, One Week, One Threshold: Silicon Qubits Cross the Fault-Tolerance Line
26 Jan 2022 - For a decade, silicon spin qubits have been quantum computing's most tantalizing "not yet." The pitch was always compelling: qubits built from the same material that powers every smartphone and data centre on earth, manufactured using processes the semiconductor industry has spent half a century perfecting. But the performance gap was real. While superconducting circuits and…
