Verifying the security of a continuous variable quantum communication protocol via quantum metrology
Lorcan O. Conlon, Biveen Shajilal, Angus Walsh +4
Quantum mechanics offers the possibility of unconditionally secure communication between multiple remote parties. Security proofs for such protocols typically rely on bounding the…
Testing the postulates of quantum mechanics with coherent states of light and homodyne detection
Lorcan O. Conlon, Angus Walsh, Yuhan Hua +5
Quantum mechanics has withstood every experimental test thus far. However, it relies on ad-hoc postulates which require experimental verification. Over the past decade there has be…
Multiparameter estimation with two qubit probes in noisy channels
Lorcan. O. Conlon, Ping Koy Lam, Syed. M. Assad
This work compares the performance of single and two qubit probes for estimating several phase rotations simultaneously under the action of different noisy channels. We compute the…
Efficient Light Propagation Algorithm using Quantum Computers
Chanaprom Cholsuk, Siavash Davani, Lorcan O. Conlon +2
Quantum algorithms can potentially overcome the boundary of computationally hard problems. One of the cornerstones in modern optics is the beam propagation algorithm, facilitating…
Discriminating mixed qubit states with collective measurements
Lorcan O. Conlon, Falk Eilenberger, Ping Koy Lam +1
It is a central fact in quantum mechanics that non-orthogonal states cannot be distinguished perfectly. This property ensures the security of quantum key distribution. It is theref…
Optimal Single Qubit Tomography: Realization of Locally Optimal Measurements on a Quantum Computer
Bacui Li, Lorcan O. Conlon, Ping Koy Lam +1
Quantum bits, or qubits, are the fundamental building blocks of present quantum computers. Hence, it is important to be able to characterize the state of a qubit as accurately as p…
