Efficient Quantum Implementation of Dynamical Mean Field Theory for Correlated Materials
Norman Hogan, Efekan Kökcü, Thomas Steckmann +6
The accurate theoretical description of materials with strongly correlated electrons is a formidable challenge in condensed matter physics and computational chemistry. Dynamical Me…
Quantum Sensing using Geometrical Phase in Qubit-Oscillator Systems
Nishchay Suri, Zhihui Wang, Tanay Roy +2
We present a quantum sensing protocol for coupled qubit-oscillator systems that surpasses the standard quantum limit (SQL) by exploiting a geometrical phase. The signal is encoded…
Combining Error Detection and Mitigation: A Hybrid Protocol for Near-Term Quantum Simulation
Dawei Zhong, William Munizzi, Huo Chen +1
Practical implementation of quantum error correction is currently limited by near-term quantum hardware. In contrast, quantum error mitigation has demonstrated strong promise for i…
Algebraic Compression of Free Fermionic Quantum Circuits: Particle Creation, Arbitrary Lattices and Controlled Evolution
Efekan Kökcü, Daan Camps, Lindsay Bassman Oftelie +3
Recently we developed a local and constructive algorithm based on Lie algebraic methods for compressing Trotterized evolution under Hamiltonians that can be mapped to free fermions…
Ground state energy and magnetization curve of a frustrated magnetic system from real-time evolution on a digital quantum processor
Aaron Szasz, Ed Younis, Wibe Albert de Jong
Models of interacting many-body quantum systems that may realize new exotic phases of matter, notably quantum spin liquids, are challenging to study using even state-of-the-art cla…
AC/DC: Automated Compilation for Dynamic Circuits
Siyuan Niu, Efekan Kokcu, Anupam Mitra +6
Dynamic quantum circuits incorporate mid-circuit measurements and feed-forward operations originally intended to realize Quantum Error Correction. This paradigm has recently been u…
