Observation of Dynamical Quantum Phase Transitions with Correspondence in an Excited State Phase Diagram. [PDF]

Physical Review Letters, 2020
Dynamical quantum phase transitions are closely related to equilibrium quantum phase transitions for ground states. Here, we report an experimental observation of a dynamical quantum phase transition in a spinor condensate with correspondence in an ...

Newton's Cradle and Quantum Observation

Terry's Archive Online, 2019
This paper defines quantum observation as conversion of tiny (attojoule or less) packets of energy and momentum into statistically irreversible Boltzmann heat. Under this definition, quantum waves never “collapse” but instead grow so fractally convoluted

Observation of a Many-Body Dynamical Phase Transition with a 53-Qubit Quantum Simulator [PDF]

Nature, 2017
A quantum simulator is a type of quantum computer that controls the interactions between quantum bits (or qubits) in a way that can be mapped to certain quantum many-body problems.

Observation of a non-Hermitian phase transition in an optical quantum gas [PDF]

Science, 2020
A dissipative quantum gas of light Our textbook understanding of quantum systems tends to come from modeling these systems isolated from the environment.

Observation of PT -symmetric quantum coherence in a single-ion system

, 2021
Parity-time ($\mathcal{PT}$)-symmetric systems, featuring real eigenvalues despite their non-Hermitian nature, undergo spontaneous $\mathcal{PT}$ symmetry breaking at the exceptional point (EP).

Direct Observation of Quantum Anomalous Vortex in Fe(Se,Te)

Physical Review X, 2023
Vortices are topological defects of type-II superconductors in an external magnetic field. In a similar fashion to a quantum anomalous Hall insulator, quantum anomalous vortices (QAV) spontaneously nucleate due to orbital-and-spin exchange interaction ...

Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer

Communications Physics, 2023
The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. If a non-destructive, minimally-disturbing interaction coupling a particle property to a pointer is implemented on each arm
