Detecting two photons with one molecule
Saumya Biswas, S. J. van Enk
We apply input-output theory with quantum pulses [AH Kiilerich, K Mølmer, Phys. Rev. Lett. {\bf 123}, 123604 (2019)] to a model of a new type of two-photon detector consisting of o…
Electron vortex beams in non-uniform magnetic fields
Abhijeet Melkani, S. J. van Enk
We consider the quantum theory of paraxial non-relativistic electron beams in non-uniform magnetic fields, such as the Glaser field. We find the wave function of an electron from s…
The Heisenberg picture of photodetection
Saumya Biswas, S. J. van Enk
We construct a class of Hamiltonians that describe the photodetection process from beginning to end. Our Hamiltonians describe the creation of a photon, how the photon travels to a…
Quantum Networks for Single Photon Detection
Tzula B. Propp, S. J. van Enk
Single photon detection generally consists of several stages: the photon has to interact with one or more charged particles, its excitation energy will be converted into other form…
On Nonlinear Amplification: Improved Quantum Limits for Photon Counting
Tzula B. Propp, S. J. van Enk
We show that detection of single photons is not subject to the fundamental limitations that accompany quantum linear amplification of bosonic mode amplitudes, even though a photode…
Loop State-preparation-and-measurement tomography of a two-qubit system
M. E. Feldman, G. K. Juul, S. J. Van Enk +1
We experimentally demonstrate that loop state-preparation-and-measurement (SPAM) tomography is capable of detecting correlated errors in a two-qubit system. We prepare photon pairs…
