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," ...

The OCU group said, "This is the first example of practical quantum algorithms, which make quantum chemical calculations realizable on quantum computers equipped with a sizable number of qubits. These ...

A quantum number describes the energies of electrons in atoms. Each quantum number specifies the value of a conserved quantity in the dynamics of the quantum system. Since any quantum system can have ...

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 ...
