Hot Carrier Thermalization and Josephson Inductance Thermometry in a Graphene-based Microwave Circuit

Raj Katti, Harpreet Arora, Olli-Pentti Saira +5

Due to its exceptional electronic and thermal properties, graphene is a key material for bolometry, calorimetry, and photon detection. However, despite graphene's relatively simple…

Fast imaging of single photons in quantum assisted optical interferometers

Andrei Nomerotski, Jonathan Schiff, Paul Stankus +5

We describe a new technique of quantum astrometry, which potentially can improve the resolution of optical interferometers by orders of magnitude. The approach requires fast imagin…

Quantum-Assisted Optical Interferometers: Instrument Requirements

Andrei Nomerotski, Paul Stankus, Anže Slosar +17

It has been recently suggested that optical interferometers may not require a phase-stable optical link between the stations if instead sources of quantum-mechanically entangled pa…

Modification of electron-phonon coupling by micromachining and suspension

Olli-Pentti Saira, Matthew H. Matheny, Libin Wang +2

Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing…

Nonequilibrium thermodynamics of erasure with superconducting flux logic

Olli-Pentti Saira, Matthew H. Matheny, Raj Katti +5

We implement a thermal-fluctuation driven logical bit reset on a superconducting flux logic cell. We show that the logical state of the system can be continuously monitored with on…

Harnessing Fluctuations in Thermodynamic Computing via Time-Reversal Symmetries

Gregory Wimsatt, Olli-Pentti Saira, Alexander B. Boyd +4

We experimentally demonstrate that highly structured distributions of work emerge during even the simple task of erasing a single bit. These are signatures of a refined suite of ti…
