Cryogenic Embedded System to Support Quantum Computing: From 5-nm FinFET to Full Processor

Quantum computing can enable novel algorithms infeasible for classical computers. For example, new material synthesis and drug optimization could benefit if quantum computers offered more quantum bits (qubits). One obstacle for scaling up quantum computers is the connection between their cryogenic qubits at temperatures between a few millikelvin and a few kelvin (depending on qubit […]

Voltage biases are often required to bias Qubits, and yet applying a static bias requires separate chip wires, dramatically increasing the system complexity. An ideal approach would be having a nonvolatile digital or analog memory to avoid these issues. This article shows floating-gate (FG) structures could be used to set and forget potentials and tunnel […]
