Benchmarking Simulations · [May 3, 02:27 PM]
What are good candidates for benchmarking, say a quantum error correction proposal or a specific qip proposal, for simulation or experimental tests?
Of course we all know that quantum computer is a device that does mainly quantum error correction and some little computation on the side [allegory due to Steane?]. So many suspect that the best benchmark might be a nice 5 qubit error correcting code… It has lots of entanglement, superpositions, mutual measurements, damn hard preparations, etc… Well, then maybe it is too hard then.
I don’t even want to think about factoring 35 or searching a database… Too hard to program, too hard to benchmark…
I have been thinking about preparing a cat state $|000\rangle+|111\rangle$, or Deutsch-Jozsa with 3 qubits… They need entangling operations, just one measurement step, and are simple enough.
Although, you can try simulating about 10 spin particles using exact Hamiltonian dynamics, I would still like to have most of those spins acting as some sort of bath… Or maybe I should go with some sort of bosonic bath with a small cut-off?
And then all of this is simply going to produce a simple graph…
