Novel Trade-offs in 5 nm FinFET SRAM Arrays at Extremely Low Temperatures

Complementary metal–oxide–semiconductor (CMOS)-based computing promises drastic improvement in performance at extremely low temperatures (e.g., 77 K, 10 K). The field of extremely low temperature CMOS-environment-based computing holds the promise of delivering remarkable enhancements in both performance and power consumption. Static random access memory (SRAM) plays a major role in determining the performance and efficiency of […]

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 […]

Millimeter-Waves to Terahertz SISO and MIMO Continuous Variable Quantum Key Distribution

With the exponentially increased demands for large bandwidth, it is important to think about the best network platform as well as the security and privacy of the information in communication networks. Millimeter (mm)-waves and terahertz (THz) with high carrier frequencies are proposed as the enabling technologies to overcome Shannon’s channel capacity limit of existing communication […]

Cryogenic Floating-Gate CMOS Circuits for Quantum Control

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 […]
