Harmonic Control of Dynamical Freezing in Programmable Rydberg Atom Arrays
Madhumita Sarkar, Ben Zindorf, Bhaskar Mukherjee +2
Periodic driving enables the engineering of complex quantum matter, yet in interacting systems it generically leads to energy absorption, which limits the lifetime of the engineere…
All You Need is pi: Quantum Computing with Hermitian Gates
Ben Zindorf, Sougato Bose
Universal gate sets for quantum computation, when single and two qubit operations are accessible, include both Hermitian and non-Hermitian gates. Here we utilize the fact that any…
How "Quantum" is your Quantum Computer? Macrorealism-based Benchmarking via Mid-Circuit Parity Measurements
Ben Zindorf, Lorenzo Braccini, Debarshi Das +1
To perform meaningful computations, Quantum Computers (QCs) must scale to macroscopic levels - i.e., to a large number of qubits - an objective pursued by most quantum companies. H…
Nonclassicality of a Macroscopic Qubit-Ensemble via Parity Measurement Induced Disturbance
Lorenzo Braccini, Debarshi Das, Ben Zindorf +3
We propose an experimental scheme to test the nonclassicality of a macroscopic ensemble of qubits, through the violation of the classical notion of macrorealism (MR) via the fundam…
Multi-Controlled Quantum Gates in Linear Nearest Neighbor
Ben Zindorf, Sougato Bose
Multi-controlled single-target (MC) gates are some of the most crucial building blocks for varied quantum algorithms. How to implement them optimally is thus a pivotal question. To…
Efficient Implementation of Multi-Controlled Quantum Gates
Ben Zindorf, Sougato Bose
We present an implementation of multi-controlled quantum gates which provides significant reductions of cost compared to state-of-the-art methods. The operator applied on the targe…
