Quantum computing could break cryptographic keys in minutes, posing a major threat to crypto security. Current cryptographic ...

The punishingly cold temperatures and fragile quantum states at the heart of a quantum computer put extreme constraints on the electronics that support them. So far, quantum computing companies have ...

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This ...

Japan has switched on the first quantum computer that has been designed and built with components from the country. The system is now ready to take on workloads from its base at the University of ...

An experiment with superconducting qubits opens the door to determining whether quantum devices could be less energetically ...

Quantum computers represent a breakthrough comparable to the move from valves to transistors in computer engineering. It doesn't just mean processing data faster; it means processing data in ways that ...
