Fault Tolerant Quantum Computers are not near term.
Can we still use the NISQ devices to outperform the Classical Computation?
Transverse field Ising Model in 127 qubits.
Expected to be extremely hard to simulate in the highly entangled regime.
IBM: Geometry;
Hamiltonian: Trotterisation
First order Trotter
Cirquit and Characterisation
Zero Noise Estimation and Probabilistic Error Correction
Comparison at Low Entanglement Limit
Prediction beyond classical (?)
Questions:
Is this Quantum Supremacy?
That is, Is there really no ways to simulate (part of) this circuit efficiently, classically?
Can all parts of the circuit be simulated efficiently, classically?
