In recent years, research and development on quantum computers has made considerable progress. Quantum chemical calculations for electronic structures of atoms and molecules are attracting great ...

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, ...

Conventional computers use bits, represented by zeros and ones, to transmit information, whereas quantum computers use quantum bits (qubits) instead. Similar to bits, qubits have two main states or ...

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 ...

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 ...

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 ...

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those ...

The scale of chemistry simulations with quantum computing has increased dramatically in just the last few months. In the ...

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 ...
