The Heisenberg limit for laser coherence

no code implementations11 Sep 2020 Travis J. Baker, Seyed N. Saadatmand, Dominic W. Berry, Howard M. Wiseman

For an ideal laser beam [1, 2, 3], it can be thought of roughly as the number of photons emitted consecutively into the beam with the same phase.

Linear Gaussian Quantum State Smoothing: Understanding the optimal unravelings for Alice to estimate Bob's state

no code implementations31 Aug 2020 Kiarn T. Laverick, Areeya Chantasri, Howard M. Wiseman

By 'optimal choice' we mean the choice for Bob that will maximize the purity improvement of Alice's smoothed state compared to her filtered state (an estimated state based only on Alice's past measurement record).
