Optical Fiber could Boost Power of Superconducting Quantum Computers

White arrow points to tiny fiber running vertically through large metal device (cryostat)
NIST physicists measured and controlled a superconducting quantum bit (qubit) using light-conducting fiber (indicated by white arrow) instead of metal electrical cables like the 14 shown here inside a cryostat. By using fiber, researchers could potentially pack a million qubits into a quantum computer rather than just a few thousand.

The secret to building superconducting quantum computers with massive processing power may be an ordinary telecommunications technology – optical fiber.

Physicists at the National Institute of Standards and Technology (NIST) have measured and controlled a superconducting quantum bit (qubit) using light-conducting fiber instead of metal electrical wires, paving the way to packing a million qubits into a quantum computer rather than ...
