High-Fidelity Electron Spin Gates for Scaling Diamond Quantum Register

Timo Joas, Florian Ferlemann, Roberto Sailer +9

Diamond is a promising platform for quantum information processing as it can host highly coherent qubits that could allow for the construction of large quantum registers. A prerequ…

Quantum Metrology with Strongly Interacting Spin Systems

Hengyun Zhou, Joonhee Choi, Soonwon Choi +10

Quantum metrology makes use of coherent superpositions to detect weak signals. While in principle the sensitivity can be improved by increasing the density of sensing particles, in…

Probing quantum thermalization of a disordered dipolar spin ensemble with discrete time-crystalline order

Joonhee Choi, Hengyun Zhou, Soonwon Choi +8

We investigate thermalization dynamics of a driven dipolar many-body quantum system through the stability of discrete time crystalline order. Using periodic driving of electronic s…

Highly sensitive macro-scale diamond magnetometer operated by dynamical decoupling sequence with coplanar waveguide resonator

Yuta Masuyama, Kousuke Mizuno, Hayato Ozawa +5

Ultimate sensitivity for quantum magnetometry using nitrogen-vacancy (NV) centers in diamond is limited by number of NV centers and coherence time. Microwave irradiation with a hig…

Observation of discrete time-crystalline order in a disordered dipolar many-body system

Soonwon Choi, Joonhee Choi, Renate Landig +11

Understanding quantum dynamics away from equilibrium is an outstanding challenge in the modern physical sciences. It is well known that out-of-equilibrium systems can display a ric…

Nonvolatile quantum memory enables sensor unlimited nanoscale spectroscopy of finite quantum systems

Matthias Pfender, Nabeel Aslam, Hitoshi Sumiya +5

In nanoscale metrology applications, measurements are commonly limited by the performance of the sensor. Here we show that in nuclear magnetic resonance (NMR) spectroscopy measurem…
