Exploiting ionization dynamics in the nitrogen vacancy center for rapid, high-contrast spin and charge state initialization

Daniel Wirtitsch, Georg Wachter, Sarah Reisenbauer +6

We propose and experimentally demonstrate a method to strongly increase the sensitivity of spin measurements on nitrogen-vacancy (NV) centers in diamond, which can be readily imple…

High-dimensional quantum communication with scalable photonic entanglement in time and frequency

Kai-Chi Chang, Murat Can Sarihan, Nicky Kai Hong Li +13

High-dimensional photonic entanglement holds significant promise for advancing quantum communication, computation, and metrology. For example, large-alphabet quantum communication…

50-km fiber interferometer for testing gravitational signatures in quantum interference

Haocun Yu, Dorotea Macri, Thomas Morling +10

Quantum mechanics and general relativity are the foundational pillars of modern physics, yet experimental tests that combine the two frameworks remain rare. Measuring optical phase…

Robust certification of non-projective measurements: theory and experiment

Raphael Brinster, Peter Tirler, Shishir Khandelwal +7

Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…

Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions

Clemens Niederegger, Tatiana Vovk, Elias Starchl +1

Continuous monitoring of one-dimensional free fermionic systems can generate phenomena reminiscent of quantum criticality, such as logarithmic entanglement growth, algebraic correl…

Gravitational and other shifts of whispering gallery and gravitational state interference patterns of light neutral particles

V. V. Nesvizhevsky, J. A. Pioquinto, K. Schreiner +7

We discuss small shifts in the interference patterns of gravitational and whispering gallery quantum states that can be observed with neutrons, atoms, antiatoms, muonium, positroni…
