Quantum-enhanced interferometry with large heralded photon-number states
G. S. Thekkadath, M. E. Mycroft, B. A. Bell +11
Quantum phenomena such as entanglement can improve fundamental limits on the sensitivity of a measurement probe. In optical interferometry, a probe consisting of entangled phot…
Tuning between photon-number and quadrature measurements with weak-field homodyne detection
G. S. Thekkadath, D. S. Phillips, J. F. F. Bulmer +10
Variable measurement operators enable the optimization of strategies for testing quantum properties and the preparation of a range of quantum states. Here, we experimentally implem…
Terahertz-driven phase transition applied as a room-temperature terahertz detector
Christopher G. Wade, Matteo Marcuzzi, Emanuele Levi +4
There are few demonstrated examples of phase transitions that may be driven directly by terahertz-frequency electric fields, and those that are known require field strengths exceed…
Intrinsic Optical Bistability in a Strongly-Driven Rydberg Ensemble
Natalia R. de Melo, Christopher G. Wade, Nikola Sibalic +3
We observe and characterize intrinsic optical bistability in a dilute Rydberg vapor. The bistability is characterized by sharp jumps between states of low and high Rydberg occupanc…
Real-Time Near-Field Terahertz Imaging with Atomic Optical Fluorescence
Christopher G. Wade, Nikola Šibalić, Natalia R. de Melo +3
Terahertz (THz) near-field imaging is a flourishing discipline [1], with applications from fundamental studies of beam propagation [2,3] to the characterisation of metameterials [4…
Driven-dissipative many-body systems with mixed power-law interactions: Bistabilities and temperature-driven non-equilibrium phase transitions
Nikola Šibalić, Christopher G. Wade, Charles S. Adams +2
We investigate the non-equilibrium dynamics of a driven-dissipative spin ensemble with competing power-law interactions. We demonstrate that dynamical phase transitions as well as…
