Rebooting Quantum Computing.

Hardware R&D projects in quantum computing are mostly divided into the sub areas of qubits, cryo-CMOS control, and control based on Josephson junction electronics. This paper makes the case that hybrid solutions are possible and should give better results. Specifically, there is recent work demonstrating how to trade the performance of qubits for the energy dissipation of the control electronics. In addition, reversible logic can have properties that lie in between those of cryo-CMOS and Josephson junction electronics, forming an “impedance matcher” that allows all three technologies to be used together. The idea of hybridization also applies to Rebooting Computing's goal of picking the successor to Moore's law from a series of options. Instead, this paper suggests a second reboot that considers hybrids of several of the originally proposed approaches.
