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, ...

Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of ...

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 ...

Researchers have identified a “nightmare scenario” calculation related to exotic types of quantum matter that would be impossible to solve, even for a very efficient quantum computer. Without the ...

The simplified formula was developed to analyze local quantum entanglement in nanoscale materials. Credit: Osaka Metropolitan University Once described by Einstein as "spooky action at a distance," ...
