Physicists have built a real-number version of quantum mechanics that makes all the same predictions as the standard theory, ...

Quantum mechanics has long relied on complex numbers to describe the strange behavior of particles, from tunneling to ...

Another quantum computing record has been broken. A team has built a quantum computer with the largest ever number of so-called logical qubits, or quantum bits. Unlike standard qubits, logical qubits ...

Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, ...

Once described by Einstein as “spooky action at a distance,” quantum entanglement may now seem less intimidating in light of new research findings. Osaka Metropolitan University physicists have ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

IBM’s Eagle quantum computer completed a calculation that stumped the conventional supercomputer it was pitted against. Quantum computers have sparked excitement for a few decades, but researchers ...

SAN JOSE, Calif., — Scientists at IBM’s Almaden Research Center have performed the world’s most complicated quantum-computer calculation to date. They caused a billion billion custom-designed ...

IBM, ORNL and Cleveland Clinic used quantum computing to model tritium-producing molten salts for fusion energy—see the ...

Researchers have investigated the capability of known quantum computing algorithms for fault-tolerant quantum computing to simulate the laser-driven electron dynamics of excitation and ionization ...
