Quantum computers need classical computing to be truly useful - New Scientist

Yonathan Cohen at Quantum Machines speaking at AQC25 conferenceQuantum Machines A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical computers are vital for controlling quantum computers, decoding the results of their calculations and even developing new techniques for manufacturing quantum computers in future. Quantum computers are made from qubits – quantum objects that may come in the form of extremely cold atoms or tiny superconducting circuits. The more qubits that a quantum computer has, the more computationally powerful it gets. Advertisement Receive a weekly dose of discovery in your inbox.
