Online meetup: Quantum computing using photons

The purpose of the community is to make knowledge about quantum computation accessible and promote sharing of ideas and advances in the field.We hope to enable a fruitful exchange between the academic community, engineers, entrepreneurs, and industry leaders, in the endeavor to create a multidisciplinary work and thought environments.https://qubit.community

Schedule:20:30 - Opening20:40 - Prof. Barak Dayan- Introduction to quantum computing with photons and atoms21:30 - Prof. Terry Rudolph- How to stop worrying and love the photonHow to stop worrying and love the photon, Prof. Terry RudolphAbstract: The challenges for building a quantum computer out of photons differ in many respects to those of matter-based qubit approaches. Optical photons suffer completely negligible environment decoherence even at room temperature, their interaction Hamiltonians are not hueristic, there is no cross talk, they network easily into arbitrary geometries and, perhaps most critically, measurements - the critical element for entropy reduction to achieve fault tolerance - are sharp and extremely fast. The obvious question “well, where the &amp;^$% is my quantum computer then?” - more frequently asked a little more politely like this: “well, what is hard for photons?” - typically evokes a response along the lines of “well, because photons don’t interact two-qubit gates have to be performed non-deterministically”. A-priori it seems this answer is essentially identical to “well, because photons don’t interact useful entanglement needs to be generated non-deterministically” In this talk I will explain why, once you free your mind from tyrannical qubitist ways of thinking, the latter response is incorrect. By the end of the talk I hope the listener will be convinced to go out and look at the stars tonight and view them a little differently.Introduction to quantum computing with photons and atoms, Prof. Barak Dayan Abstract: I will introduce the principles of photonic quantum computation and its potential to become the leading platform towards full-scale fault-tolerant quantum computing. As logic gates (classical or quantum) are inherently nonlinear, I will discuss the physical sources of nonlinearity at the single photon level. I will then present the state-of-the-art of photon-atom quantum gates, and the model of measurement-based quantum computation, and conclude by discussing the potential of combining these two platforms.
