Is the Optical Fiber Your IT Department Uses the Key to Super-Superconducting Quantum Computers?
Optical Fiber Could Boost Power of Superconducting Quantum Computers 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 […]

The Cryotron: Superconducting Nano-Wire May be Enroute to Your Quantum Computer
Nanowire could provide a stable superconducting transistor + Most metals lose resistance and become superconducting at extremely low temperatures, usually just a few degrees above absolute zero. They’re used to sense magnetic fields, especially in highly sensitive situations like monitoring brain activity. They also have applications in both quantum and classical computing. Berggren said his […]

Indium Arsenide: Solution for a Scalable Quantum Computer? Above image is of a nanomechanical router. Full caption: “The research team has invented a component, called a nanomechanical router, that emits quantum information carried by light particles (photons) and routes them into different directions inside a photonic chip. Photonic chips are like computer microchips — only, […]
Qubit Resilience via Topological Insulators
Qubit Resilience via Topological Insulators. Purdue University scientists’ efforts have brought insulating qubits [quantum bits] one step closer to scalable-reality. A new material developed has been engineered into a “nanoribbon”, conducting electrical current on the surface but not below. Termed a “topological insulator”, the strip, when connected to two superconductor electrical leads composes a device called […]
