Improving Gaussian channel simulation using non-unity gain heralded quantum teleportation
Biveen Shajilal, Lorcán O. Conlon, Angus Walsh +5
Gaussian channel simulation is an essential paradigm in understanding the evolution of bosonic quantum states. It allows us to investigate how such states are influenced by the env…
Attainability of quantum state discrimination bounds with collective measurements on finite copies
Lorcan Conlon, Jin Ming Koh, Biveen Shajilal +3
One of the fundamental tenets of quantum mechanics is that non-orthogonal states cannot be distinguished perfectly. When distinguishing multiple copies of a mixed quantum state, a…
Comparison of estimation limits for quantum two-parameter estimation
Simon K. Yung, Lorcan O. Conlon, Jie Zhao +2
Measurement estimation bounds for local quantum multiparameter estimation, which provide lower bounds on possible measurement uncertainties, have so far been formulated in two ways…
Strong cubic phase shifts on the photonic vacuum state
Hao Jeng, Lorcan Conlon, Ping Koy Lam +1
Addition of photons to coherent states is shown to produce effects that display remarkable similarities with cubic phase shifts acting on the vacuum state, with fidelities in exces…
Holevo Cramér-Rao bound: How close can we get without entangling measurements?
Aritra Das, Lorcán O. Conlon, Jun Suzuki +3
In multi-parameter quantum metrology, the resource of entanglement can lead to an increase in efficiency of the estimation process. Entanglement can be used in the state preparatio…
Dual Open Atom Interferometry for Compact and Mobile Quantum Sensing
Yosri Ben-Aïcha, Zain Mehdi, Christian Freier +12
We demonstrate an atom interferometer measurement protocol compatible with operation on a dynamic platform. Our method employs two open interferometers, derived from the same atomi…
Role of the extended Hilbert space in the attainability of the Quantum Cramér-Rao bound for multiparameter estimation
Lorcan O. Conlon, Jun Suzuki, Ping Koy Lam +1
The symmetric logarithmic derivative Cramér-Rao bound (SLDCRB) provides a fundamental limit to the minimum variance with which a set of unknown parameters can be estimated in an un…
