In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications targeted by quantum computers, such as quantum chemistry, ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the ...

Imagine a future where quantum computers supercharge machine learning—training models in seconds, extracting insights from ...

Scientists map how quantum computer errors persist and link over time, revealing hidden memory that could reshape error ...

Two quantum information theorists have solved a decades-old problem that will free up quantum computing power. University of Sydney quantum researchers Dominic Williamson and Nouédyn Baspin have ...

The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. May 7 ...

Quantum error correction (QEC) and fault-tolerant computation provide the critical framework for realising reliable quantum processors in the presence of inevitable ...

On Thursday, Amazon.Com Inc (NASDAQ:AMZN) Amazon Web Services (AWS) announced Ocelot, its new quantum computing chip that can reduce the costs of implementing quantum ...
