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

A protocol to characterize device performance in quantum error correction promises to improve experiments by exploiting information about the noise. @evanhockings @AC_Doherty go.aps.org/3QUiUbH

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!

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 usyd.wd3.myworkdayjobs.com/USYD_EXTERNAL_…

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

@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

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! arxiv.org/abs/2404.17570

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 theconversation.com/mind-bending-m…

@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

@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 science.org/doi/abs/10.112…

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!
