More fun results from Quantinuum. Two-qubit gate fidelity better than 99.9% across ALL qubit pairs in a commercial quantum computer, and a new Quantum Volume record of 2^20.

Don't know much about the theory but I can tell you this is an amazing machine built with a ton of blood sweat and tears! Great to see H2 out in the world doing things

@mattjmcewen showing us some “biblically accurate angels” while discussing surface codes utilizing time dynamics at #qec23

Fun and informative talk.

[Ciarán Ryan-Anderson @quCiaran]

If you are interested in developing QEC or related software (e.g., realistic simulation, QEC, etc.) for the QCCD ion trap architecture @QuantinuumQC, feel free to contact me, @nachi182, or @DavidHa03746758. #qec23

[Error correction zoo @theeczoo]

Ciaran Ryan-Anderson @QuantinuumQC discusses gate implementation of two blocks of the five-qubit code. A FT logical gate can be done with the help of flag qubits. https://t.co/DdDSkwDG3X

Natalie Brown showing off @QuantinuumQC QCCD architecture with also mid-circuit measurements used in QEC. It's cool to see ions running around the chip. Steane code paper (Ryan-Anderson etc al 2021) recommended (students especially) for experimental QEC proposal #QEC23

[Balint Pato @balopat]

@quCiaran of @QuantinuumQC on FT logical gates on real hardware. And these gates are not all even transversal, using piecable FT instead. Great to see flag qubits in real devices. WASM architecture to compile Rust/C++ decoders into QASM code is cool. #QEC23

[Earl T Campbell @earltcampbell]

Natalie brown advertises quantinuum’s roadmap and progress towards their next gen X junction ion trap device.

[Earl T Campbell @earltcampbell]

NB: Dephasing (and leakage) errors, especially during shuttling ions, is the main bottleneck in getting quantinuum to break-even. #qec23

[Earl T Campbell @earltcampbell]

NB: juicy very early results on surface code QEC experiments by quantinuum. #qec23

[Earl T Campbell @earltcampbell]

Ryan continues the quantinuum two parter and general theme for the day so far: QEC experiments are here! #qec23

[Dulwich Quantum Computing @DulwichQuantum]

If only I could remove this one CNOT gate!

[Natalie Brown @nachi182]

Very excited for our new paper with @cgranade and @quCiaran and all the wonderful collaborators at @microsoft and @QuantinuumQC.

We demonstrate the control flow necessary for realizing Magic State distillation and Repeat-until-success circuits.

It's okay to tweet your paper, right? Everybody does this, surely. https://t.co/POMnWOxEux

[Natalie Brown @nachi182]

Always a pleasure to hear Patty Lee, chief scientist at @QuantinuumQC discuss how our company is growing, developing and pushing the limits of #quantumcomputing. @IEEEQuantumWeek @IEEEQuantum

Here she show cases our H2 “racetrack” trap as well as junction transport techniques.

[Tony @Tonyransford]

Insane amount of work from a huge team getting this system going!!! So proud of @QuantinuumQC for being open about all the hardware, its easy with spec's like these https://t.co/sISrlsjdT5 (scroll down for a data sheet). LETS GO!! #quantumcomputing #quantum

[Michael Newman @MikeNewmQuantum]

some impressive specs in https://t.co/wSyPKV4GBV
