Measurement-based cooling of many-body quantum systems
Tarek A. Elsayed
We introduce a novel technique for efficiently cooling many-body quantum systems with unknown Hamiltonians down to their ground states with a high fidelity. The technique involves…
Cooling classical many-spin systems using feedback control
Tarek A. Elsayed, Boris V. Fine
We propose a technique for polarizing and cooling finite many-body classical systems using feedback control. The technique requires the system to have one collective degree of free…
Quantum key distribution based on the quantum eraser
Tarek A. Elsayed
Quantum information and quantum foundations are becoming popular topics for advanced undergraduate courses. Many of the fundamental concepts and applications in these two fields, s…
Deterministic secure quantum communication with and without entanglement
Tarek A. Elsayed
We present a protocol for sending a message over a quantum channel with different layers of security that will prevent an eavesdropper from deciphering the message without being de…
Entangled Quantum Dynamics of Many-Body Systems using Bohmian Trajectories
Tarek A. Elsayed, Klaus Mølmer, Lars Bojer Madsen
Bohmian mechanics is an interpretation of quantum mechanics that describes the motion of quantum particles with an ensemble of deterministic trajectories. Several attempts have bee…
Probing Quantum States with Momentum Boosts
Tarek A. Elsayed, Alexej I. Streltsov
We present a technique to diagnose the condensate fraction in a one-dimensional optical lattice of weakly interacting bosons based on the dynamics of the trapped atoms under the in…
Quantum Trajectory Analysis of the Two-Mode Three-Level Atom Microlaser
Tarek A. Elsayed, Abdulaziz Aljalal
We consider a single atom laser (microlaser) operating on three-level atoms interacting with a two-mode cavity. The quantum statistical properties of the cavity field at steady sta…
