Thanks to @APSphysics for the feature about our quantum-metrology paper, just out in @PhysRevLett---and for including the very important scare quotes! physics.aps.org/articles/v17/s… journals.aps.org/prl/abstract/1…

Quantum sensing can achieve maximal quantum Fisher information about the rotation of a spin when the rotation access is unknown using a protocol inspired by simulations of closed timelike curves. Letter: go.aps.org/3xzhaOW Synopsis: go.aps.org/3XJkamA

Imagine if gamblers, investors and quantum experimentalists could bend the arrow of time?⌛ Physicists from @Cambridge_Uni & @NIST have done it, manipulating quantum entanglement to simulate what could happen if one could travel back in time. How? Read👇 phy.cam.ac.uk/news/simulatio…

Delighted that Optics & Photonics News @OPNMagazine highlighted this foundations-flavored result in its annual roundup. Congratulations to @YBYilmazQO @ParticulateDave @ABrodutch @QuantumAephraim! optica-opn.org/home/articles/…

It's easy to compress metrological quantum information: journals.aps.org/pra/pdf/10.110…

BREAKING NEWS: The Royal Swedish Academy of Sciences has decided to award the 2022 #NobelPrize in Physics to Alain Aspect, John F. Clauser and Anton Zeilinger.

Suppose we really are approaching the quantum age, when the Canadian lady at the pancake house knows the workings of spin-based quantum computers but hasn't heard of Leonard Cohen...

Bubble tea with favourite quantum optometrist! It was great to see the lab where it all happened. journals.aps.org/prl/abstract/1… quantamagazine.org/physicists-sho…

@DHLUSHelp @dhlexpressuk @DHLUS I was on the phone with these people for 4h, check their logs. They've done nothing, and offered nothing. Can I please have my passport?!

@ParticulateDave @dhlexpressuk @DHLUS @ParticulateDave You may contact your local customer service office at dhl.com/gb-en/home/cus… for support. ^MT

@dhlexpressuk @DHLUS @DHLUSHelp Now 3 days since your (3-day-late) delivery of my passport to the WRONG address. Yesterday I spent 4h calling your US and UK offices; both blamed each other. Still 0 info from you. Your service doesn't even match the worst Parisian restaurants'.

Nu är frågan: hur botar man fanatiker? Går det ens? Bra utbildning, självständigt tänkande, politisk kultur m dialog o kompromisser, fri press =viktiga element. Och har du hört talas om fanatiker med humor?

Wasn't the idea of having Patel as a minister to advocate harsher punishments...

NEW: @hilarybennmp, @YvetteCooperMP, @frankfieldteam, @normanlamb, @AngusMacNeilSNP and @spelmanc have written to the Archbishop of Canterbury asking him to chair a citizen's assembly on Brexit

Meanwhile, away from the G7... EXCL: The Archbishop of Canterbury is in talks with MPs to chair a citizen’s assembly intended to stop a no-deal Brexit. thetimes.co.uk/article/welby-…

@realDonaldTrump Mr Prez, did you not fire #JamesComey from investigating this stuff, because you said he had been unfair against #HillaryClinton? hmm...

@British_Airways Just showed up at the checkin desk before it said it would close. No-one here. Phone number on desk does not work. No help?
