Hybrid theory

Several of the group’s papers in the last year have focused on the theory behind so-called hybrid quantum algorithms — where a conventional computer and a quantum coprocessor work in tandem. These methods are typically variational because the quantum machine has a number of parameters (essentially, knobs that can be Read more…

Good vibrations

Working with Alexander Mayorov from Cambridge and Xiao Shan from Oxford Chemistry, we’ve looked into the prospects for modelling molecular vibrations using a quantum computer. Vibrations are are the core of many important phenomena such as spectral properties, energy transfer, and molecular bonding — but they are hard to model Read more…

Twirling

For quantum error correction, if the error rate of our physical components is below a certain error threshold, we can decrease the overall computational error indefinitely by scaling up the code. To obtain the value of such a threshold, we need to simulate the quantum error correction circuit, which can only be Read more…

Simon speaks on Y Combinator

Simon Benjamin was recently featured on the Y Combinator blog, a seed accelerator which has seeded companies like Dropbox, Airbnb, Reddit and Twitch. In the episode, which you can view here, Simon discusses the different approaches for constructing and scaling a quantum computer.
