Andrew Doherty

Theoretical Quantum Physicist at the University of Sydney.

[Evan Hockings @evanhockings]

My first paper—with @AC_Doherty and Robin Harper—is now out in PRX Quantum! More to come soon :)

[Andrew Doherty @AC_Doherty]

@WoodsMischa hi Mischa! you are right that the talk is not online, and it's the first time i have given it, send me an email if you want the slides

[Andrew Doherty @AC_Doherty]

Been having lots of fun here in Benasque! thanks to the organisers for a great workshop, but i refuse to repost the much less flattering photo of me at the panel this morning!

[Fault-Tolerant Quantum Technologies in Benasque @FTQTBenasque]

Back from a nice weekend full of activities! @AC_Doherty talks now about protected superconducting qubits.

[Andrew Doherty @AC_Doherty]

Come work with at Sydney in the School of Physics! We are looking for a theorist in photonics looking to start a research group, a continuing (roughly tenure-track equivalent) position https://t.co/U1ZsnwyJCf happy to answer questions

[Sydney Science @Sydney_Science]

This year we have 3 scholarships available in any relevant area of physics & astronomy, and 1 scholarship available in nanophotonics for quantum control, interstellar travel & passive cooling. Applications close 26 June. Learn more: https://t.co/DF1qivwULc

A reminder that we have an opening at Sydney for someone looking to start a research group in quantum theory. It's "level B/C" which roughly means tenure track in North American parlance. Contact me or @BartlettQuantum for info https://t.co/U1ZsnwzhrN

[Andrew Doherty @AC_Doherty]

Join us at the University of Sydney on Thursday night if you can for a fantastic public lecture by Prof Marcela Bilek

[Andrew Doherty @AC_Doherty]

anyone with questions about this position should contact me or @BartlettQuantum -- we particularly encourage applications from women

[Andrew Doherty @AC_Doherty]

Come work with us! We have a level B/C continuing position in theoretical quantum Physics at the university of Sydney. (position roughly equivalent to tenure track in North America, but you get to live in Sydney!) https://t.co/U1ZsnwzhrN

[Andrew Doherty @AC_Doherty]

We had lots of fun at our Coogee quantum theory workshop this year, now you too can be part of it, talks now posted here https://t.co/KqSqXCNf2R

[Andrew Doherty @AC_Doherty]

@clarejtbirch never do this unless you are on a US domestic flight with too much carry on

[Andrew Doherty @AC_Doherty]

@meQuanics maybe we should discuss: they describe a Mach-Zehnder so a 2-2 optical switch, I put the photon in and get it out in one of 2 places depending on V, there may be some dependence of loss on which output I get but that should be a small effect

[Andrew Doherty @AC_Doherty]

Congrats to @psiquantum! I am biased but this is very exciting to me. Particularly the "next generation technologies" for sources, switches, delays, detectors, and fiber-to-chip coupling. Photonic quantum computing still in the race! https://t.co/Cy13vdF710

[Sydney Quantum Academy @SydneyQuantum]

What a huge week for #quantum!
@Sydney_Uni has been awarded $18.4 million to establish 'Quantum Australia' - a new national centre to help grow Australia's quantum industry and ecosystem.

Do you know about the fascinating mathematical ideas behind post-quantum cryptography? I wrote about how Australia should be training more people with deep mathematical skills for PQC: Mind-bending maths could stop quantum hackers, but few understand it https://t.co/engKqAFZkv

[Andrew Doherty @AC_Doherty]

@meQuanics typical definition of insertion loss would include getting into and out of the device, so i would assume that is included, however note that this is on chip so losses like getting on and off the chip should not be included, should be loss with switch as opposed to without

[Andrew Doherty @AC_Doherty]

@fgrosshans @letonyo @michael_nielsen It is in the Basdevant, Dalibard quantum mechanics text, they cite Weisskopf, and that seems to have every variant of this you could wish for @michael_nielsen, also things like the density and hardness of matter, visibility of compact matter, size of stars https://t.co/X73FmE5rJB

[Evan Hockings @evanhockings]

In fault-tolerant quantum computers, physical circuits implement encoded logical operations. Typically, the bulk of these physical circuits are syndrome extraction circuits, such as this one for the surface code.

This makes them a key target for noise characterisation!
