Helium's Role in Superconducting Quantum Computers

Jun 3, 2024
2 min read

Researchers in Japan have made a breakthrough in quantum computing technology, which involves utilising liquid helium as a coolant. By developing a superconducting circuit that operates at about -269°C, they can now control many quantum bits (qubits) — the basic units of quantum computers — through a single cable. This new method reduces the complexity and amount of equipment needed, potentially allowing for much larger quantum computers. This experiment highlights the crucial role of helium in achieving the extremely low temperatures necessary for advanced quantum computing.
