Background cancellation for frequency-selective quantum sensing
Ricard Puig, Nathan Constantinides, Bharath Hebbe Madhusudhana +3
A key challenge in quantum sensing is the detection of weak time dependent signals, particularly those that arise as specific frequency perturbations over a background field. Conve…

Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in…

Optimal Routing Protocols for Reconfigurable Atom Arrays
Nathan Constantinides, Ali Fahimniya, Dhruv Devulapalli +5
Neutral atom arrays have emerged as a promising platform for both analog and digital quantum processing. Recently, devices capable of reconfiguring arrays during quantum processes…
