Mapping a 50-spin-qubit network through correlated sensing
G. L. van de Stolpe, D. P. Kwiatkowski, C. E. Bradley +7
Spins associated to optically accessible solid-state defects have emerged as a versatile platform for exploring quantum simulation, quantum sensing and quantum communication. Pione…
Appearance of objectivity for NV centers interacting with dynamically polarized nuclear environment
Damian Kwiatkowski, Łukasz Cywiński, Jarosław K. Korbicz
Quantum-to-classical transition still eludes a full understanding. Out of its multiple aspects, one has recently gained an increased attention - the appearance of objective world o…
Robust All-Optical Single-Shot Readout of NV Centers in Diamond
Dominik M. Irber, Francesco Poggiali, Fei Kong +7
High-fidelity projective readout of a qubit's state in a single experimental repetition is a prerequisite for various quantum protocols of sensing and computing. Achieving single-s…
Qubit-environment Negativity versus Fidelity of conditional environmental states for an NV-center spin qubit interacting with a nuclear environment
Małgorzata Strzałka, Damian Kwiatkowski, Łukasz Cywiński +1
We study the evolution of qubit-environment entanglement, quantified using Negativity, for NV-center spin qubits interacting with an environment of C isotope partially polar…
Influence of nuclear spin polarization on spin echo signal of NV center qubit
Damian Kwiatkowski, Piotr Szańkowski, Łukasz Cywiński
We consider the spin echo dynamics of a nitrogen-vacancy center qubit based the ground state spin manifold, caused by a dynamically polarized nuclear environment. We sh…
How to detect qubit-environment entanglement generated during qubit dephasing
Katarzyna Roszak, Damian Kwiatkowski, Łukasz Cywiński
We propose a straightforward experimental protocol to test whether qubit-environment entanglement is generated during pure dephasing of a qubit. The protocol is implemented using o…
