Quantum random walks with multiphoton interference and high order correlation functions
Bryan T Gard, Robert M Cross, Petr M Anisimov +2
We show a simulation of quantum random walks with multiple photons using a staggered array of 50/50 beam splitters with a bank of detectors at any desired level. We discuss the mul…
Thwarting the Photon Number Splitting Attack with Entanglement Enhanced BB84 Quantum Key Distribution
Carl F. Sabottke, Chris D. Richardson, Petr M. Anisimov +3
We develop an improvement to the weak laser pulse BB84 scheme for quantum key distribution, which utilizes entanglement to improve the security of the scheme and enhance its resili…
Phase estimation with two-mode squeezed-vacuum and parity detection restricted to finite resources
Keith R. Motes, Petr M. Anisimov, Jonathan P. Dowling
A recently proposed phase-estimation protocol that is based on measuring the parity of a two-mode squeezed-vacuum state at the output of a Mach-Zehnder interferometer shows that Cr…
Coherent and Squeezed Vacuum Light Interferometry: Parity detection hits the Heisenberg limit
Kaushik P. Seshadreesan, Petr M. Anisimov, Hwang Lee +1
The interference between coherent and squeezed vacuum light can produce path entangled states with very high fidelities. We show that the phase sensitivity of the above interferome…
Dynamical Decoupling in Optical Fibers: Preserving Polarization Qubits from Birefringent Dephasing
Bhaskar Roy Bardhan, Petr M. Anisimov, Manish K. Gupta +4
One of the major challenges in quantum computation has been to preserve the coherence of a quantum system against dephasing effects of the environment. The information stored in ph…
Objectively discerning Autler-Townes Splitting from Electromagnetically Induced Transparency
Petr M. Anisimov, Jonathan P. Dowling, Barry C. Sanders
Autler-Townes splitting (ATS) and electromagnetically-induced transparency (EIT) both yield transparency in an absorption profile, but only EIT yields strong transparency for a wea…
