My latest research on realizing a quantum phase transition across an error threshold has just been published with @SpringerNature in @NaturePhysics!Read more here: https://t.co/BsfskMyeBy

Thanks to my wonderful collaborators at @IBMQuantum @Harvard and @UniCologne

Can you find the Nishimori cat states? We did! Using @IBMResearch's 127 qubit superconducting processor. Thanks to @guoyizhu, @simon from the U. of Cologne; Ruben Verresen, Nathanan Tantivasadakarn (now Caltech) and @AshvinVish25247 from Harvard; and my fellow IBMers.

The Nishimori transition is a staple of stat mech — one of few exact results for the random-bond Ising model famous for its spin glass phase. Moving directly through the transition, however, is an exceedingly fine-tuned manoeuvre balancing thermal fluctuations and disorder.

If you want to learn about quantum error correction. Applications are open for Quantum Error Correction Summer School 2022! - a month-long summer school on QEC. The school will cover foundation and advanced topics in both theory and experiment. Apply here:

A little update. Our first exploratory Falcon r8 processor - "ibm_peekskill" is alive. Happy to have 3 times the coherence in a large device and we are on a path for pushing the quality of our systems higher. https://t.co/MiYvmjkid6

Looking forward to reading this!

A lot of smart folks worked hard and long on this paper. I’m proud to be part of such an excellent team @awscloud. 1/4

Home is behind...
And there are many paths to tread
Through shadows to the edge of night,
Until the stars are all alight. #MessageToVoyager

Beautifully stated. Be sure to check out Dr. Preskill's post on the Quantum Frontiers blog. #gravitationalwaves https://t.co/sNbpNCRF5C

#LIGO scientists discovered Einstein’s gravitational waves…but what are they? Find out here: https://t.co/KMOJgmtqkA

[Caltech @Caltech]

.@LIGO scientists at #Caltech viewing get a well-deserved round of applause #gravitationalwaves #einsteinwasright

To do science well is to walk a tightrope between surly curmudgeon and starry-eyed cheerleader. Today is a day for cheering. #LIGO

[President Obama @POTUS44]

Einstein was right! Congrats to @NSF and @LIGO on detecting gravitational waves - a huge breakthrough in how we understand the universe.

[John Preskill @preskill]

Gabriela González: It’s been a very long road, but this is just the beginning ... We will be listening to the universe. #LIGO
