Frozen-Tree Sampling Refutes Quantum Advantage of Random Circuit Sampling
Sangchul Oh
Random circuit sampling of bitstrings from a Haar-random quantum state is widely believed to be classically intractable, and has therefore been implemented as a primary benchmark f…
Subsystem Statistics and Conditional Self-Similarity of Random Quantum States
Sangchul Oh
We analytically derive the bit-string probability distributions of subsystems of random pure states and depolarized random states using the Dirichlet distribution. We identify the…
Random Projection using Random Quantum Circuits
Keerthi Kumaran, Manas Sajjan, Sangchul Oh +1
The random sampling task performed by Google's Sycamore processor gave us a glimpse of the "Quantum Supremacy era". This has definitely shed some spotlight on the power of random q…
Cutoff phenomenon and entropic uncertainty for random quantum circuits
Sangchul Oh, Sabre Kais
How fast a state of a system converges to a stationary state is one of the fundamental questions in science. Some Markov chains and random walks on finite groups are known to exhib…
Race for Quantum Advantage using Random Circuit Sampling
Sangchul Oh, Sabre Kais
Random circuit sampling, the task to sample bit strings from a random unitary operator, has been performed to demonstrate quantum advantage on the Sycamore quantum processor with 5…
Statistical Analysis on Random Quantum Sampling by Sycamore and Zuchongzhi Quantum Processors
Sangchul Oh, Sabre Kais
Random quantum sampling, a task to sample bit-strings from a random quantum circuit, is considered one of suitable benchmark tasks to demonstrate the outperformance of quantum comp…
