Revealing the emergence of classicality in nitrogen-vacancy centers
Thomas Unden, Daniel Louzon, Michael Zwolak +2
The origin of classical reality in our quantum world is a long-standing mystery. Here, we examine a nitrogen vacancy center evolving naturally in the presence of its environment to…
Coherent control of solid state nuclear spin nano-ensembles
Thomas Unden, Nikolas Tomek, Timo Weggler +11
Detecting and controlling nuclear spin nano-ensembles is crucial for the further development of nuclear magnetic resonance (NMR) spectroscopy and for the emerging solid state quant…
Controllable Non-Markovianity for a Spin Qubit in Diamond
Jan F. Haase, Philipp J. Vetter, Thomas Unden +7
We present a flexible scheme to realize non-artificial non-Markovian dynamics of an electronic spin qubit, using a nitrogen-vacancy center in diamond where the inherent nitrogen sp…
Narrow-bandwidth sensing of high-frequency fields with continuous dynamical decoupling
Alexander Stark, Nati Aharon, Thomas Unden +5
State-of-the-art methods for sensing weak AC fields are only efficient in the low frequency domain (< 10 MHz). The inefficiency of sensing high frequency signals is due to the lack…
Sub-millihertz magnetic spectroscopy with a nanoscale quantum sensor
Simon Schmitt, Tuvia Gefen, Felix M. Stürner +13
Precise timekeeping is critical to metrology, forming the basis by which standards of time, length and fundamental constants are determined. Stable clocks are particularly valuable…
Protecting a nuclear spin from a noisy electron spin in diamond
Itsik Cohen, Thomas Unden, Fedor Jelezko +1
Although a nuclear spin is weakly coupled to its environment, due to its small gyromagnetic ratio, its coherence time is limited by the hyperfine coupling to a nearby noisy electro…
