Crossover from Fast Scrambling to Operator Confinement Tuned by an Auxiliary Qubit
Ryan Buechele, Joseph Szabo, Nandini Trivedi
We demonstrate a static, disorder-free spin chain Hamiltonian which, by tuning the coupling to an auxiliary qubit, realizes a crossover between super-ballistic, ancilla-accelerated…
Drone- and Vehicle-Based Quantum Key Distribution
Andrew Conrad, Roderick Cochran, Daniel Sanchez-Rosales +17
Quantum key distribution is a point-to-point communication protocol that leverages quantum mechanics to enable secure information exchange. Commonly, the transmitter and receiver s…
Fast-Scrambling and Operator Confinement Using an Auxiliary Qubit
Joseph Szabo, Nandini Trivedi
We introduce a minimal model for realizing a fast-to-slow scrambling transition mediated by an auxiliary central qubit (c-qubit). The c-qubit is coupled to a spin- Ising model…
Entanglement Dynamics between Ising Spins and a Central Ancilla
Joseph Szabo, Nandini Trivedi
We investigate competing entanglement dynamics in an open Ising-spin chain coupled to an external central ancilla qudit. In studying the real-time behavior following a quench from…
Local Spectroscopies Reveal Percolative Metal in Disordered Mott Insulators
Joseph C. Szabo, Kyungmin Lee, Vidya Madhavan +1
We elucidate the mechanism by which a Mott insulator transforms into a non-Fermi liquid metal upon increasing disorder at half filling. By correlating maps of the local density of…
