RedCarD: A Quantum Assisted Algorithm for Fixed-Depth Unitary Synthesis via Cartan Decomposition
Omar Alsheikh, Efekan Kökcü, Bojko N. Bakalov +1
A critical step in developing circuits for quantum simulation is to synthesize a desired unitary operator using the circuit building blocks. Studying unitaries and their generators…
Hybrid continuous-discrete-variable quantum computing: a guide to utility
A. F. Kemper, Antonios Alvertis, Muhammad Asaduzzaman +24
Quantum computing has traditionally centered around the discrete variable paradigm. A new direction is the inclusion of continuous variable modes and the consideration of a hybrid…
Approximate Message Passing for Quantum State Tomography
Noah Siekierski, Kausthubh Chandramouli, Christian Kümmerle +2
Quantum state tomography (QST) is an indispensable tool for characterizing many-body quantum systems. However, due to the exponential scaling of the cost of the protocol with syste…
Provable avoidance of barren plateaus for the Quantum Approximate Optimization Algorithm with Grover mixers
Boris Tsvelikhovskiy, Matthew Nuyten, Bojko N. Bakalov
We analyze the dynamical Lie algebras (DLAs) associated with the Grover-mixer variant of the Quantum Approximate Optimization Algorithm (GM-QAOA). When the initial state is the uni…
Connection Between Classical and Quantum Descriptions of Spin Waves Using Quantum Circuits
Daniel D. Stancil, Bojko N. Bakalov, Gregory T. Byrd
A quantum computing circuit is presented that approximates a single spin wave quantum on a linear chain of spin 1/2 particles described by a Heisenberg Hamiltonian. The circuit is…
Implementing Finite Impulse Response Filters on Quantum Computers
Aishwarya Majumdar, Bojko N. Bakalov, Dror Baron +1
While signal processing is a mature area, its connections with quantum computing have received less attention. In this work, we propose approaches that perform classical discrete-t…
