Efficient classical simulation of large-scale unitary cluster Jastrow circuits
Hrishikesh Belagali, Thomas Van Camp, R. Pradeep +3
Recent experiments on quantum computers have challenged the limits of classical computation in chemistry, simulating ground states of strongly correlated molecules. Many of these e…
Distribution Complexity of Electronic Structure Simulations on Quantum Supercomputers
Jason Necaise, Namit Anand, Gaurav Gyawali +3
Efficient simulation of strongly-interacting fermionic systems on quantum processing units (QPUs) is a challenging task due to nonlocal mode entanglement generation. However, it is…
Partially Fault-Tolerant Quantum Computation for Megaquop Applications
Ming-Zhi Chung, Ali H. Z. Kavaki, Artur Scherer +14
Partially fault-tolerant quantum computing (FTQC) has recently emerged as a promising approach for the execution of megaquop-scale circuits with millions of logical operations. In…
Distributed Quantum Computing via Adaptive Circuit Knitting
K. Grace Johnson, Aniello Esposito, Gaurav Gyawali +5
Distributing quantum workloads over many Quantum Processing Units (QPUs) is a crucial step in scaling up quantum computers toward practical quantum advantage due to the limitations…
Qudit Designs and Where to Find Them
Namit Anand, Jeffrey Marshall, Jason Saied +2
Unitary t-designs are some of the most versatile tools in quantum information theory. Their applications range from randomized benchmarking and shadow tomography, to more fundament…
Dual-unitary shadow tomography
Ahmed A. Akhtar, Namit Anand, Jeffrey Marshall +1
We introduce ``dual-unitary shadow tomography'' (DUST), a classical shadow tomography protocol based on dual-unitary brick-wall circuits. To quantify the performance of DUST, we st…
