⚛️ Curious about getting into quantum computing for quantum chemistry? Check out our new primer published in ACS InFocus. 📙 [1/4]

I'm often asked if I'll redo the 2019 quantum factoring estimate. Denser storage by yokes, smaller magic factories by cultivation, slimmer approx arithmetic by Chevignard et al… surely the cost is lower now?

Yes, it's lower now.

Finally, this project was a very fun collaboration with Dmitrii, who is an amazing undergraduate student at Duke, and Ken, without whom this would not have been possible.

Our method represents a resource-efficient way to estimate observables and has applications in both fault-tolerant and near-term quantum computing. Please check it out (arxiv.org/abs/2505.11486) — we welcome any comments!

and use this to build unbiased estimators from weighted expectation values. We then analyze when this method works and validate it via simulations, including time evolution under the Ising Hamiltonian.

Unitary errors, e.g., from fault-tolerant compilation, systematically bias observable estimates. The usual way to correct this bias is to use more non-Clifford gates. Here, we present an alternative strategy: decompose the ideal channel into a probabilistic mixture of noisy channels

Unbiased observable estimation via noisy channel mixtures for fault-tolerant quantum computation Unitary errors, such as those arising from fault-tolerant compilation of quantum algorithms, systematically bias observable estimates. Correcting this bias typically requires additional resources, suc...

We posted a new paper (arxiv.org/abs/2505.11486) on arXiv, where we present a method to unbias observable estimates in quantum circuits with unitary noise — common in fault-tolerant quantum computing.
