Seated (late) for Andrew Jordan’s (from @UofR) talk at #MCQS on “Estimating with continuous quantum measurement” #LTQI
@UofR Andrew Jordan looks at ways to monitor qubit fluorescence through photon counting or heterodyne measurements. He also investigate tomography techniques, and how to optimize the control parameters
#LTQI #MCQS
@UofR Andrew Jordan applies i tot a continuous syndrome measurement of the three qubit quantum error correcting code, by a continuous gaussian parity read-out. It (among other advantages) allows to work without an ancilla qubit.
#LTQI #MCQS
@UofR Andrew Jordan models the qubit state with a hidden markov chain, and use a Bayesian (Wonham) filter for the correction.

Now at #JapanEUWorkshop, Shuntaro Takeda on A strategy for large-scale optical quantum computing #LTQI
Shuntaro Takeda: use a deterministic approach, a loop to increase scalability. Determinism is brought by continuous variable (CV) system, which need 5 gates to be universal: 3 linear, squeezing and cubic gate (the hard one) #LTQI #JapanEUWorkshop
Shuntaro Takeda: both discrete CNOT and CV cubit gates need χ⁽³⁾ and are therefore difficult, but the latter is at least deterministic.

Now at #JapanEUWorkshop , Anthony Laing on Photonic simulations of molecular quantum dynamics #LTQI
Anthony Laing essentially looks a photnic simulation of vibrational modes of molecules
Anthony Lang looks at selective dissociation with a single quantum of vibration NH₃→NH₂+H. These molecular transition can be manipulated through control of the wavepacket. #LTQI

Now Erika Kawakami on Capacitive read-out of the Rydberg states towards the realization of a quantum computer
using electrons on helium
#LTQI #JapanEUWorkshop
Erika Kawakami: Why use electrons on helium? The system is clean: electrons float in vacuum, far prom nuclear spin and other charges. Electron qubits are 1µm away, which will be useful for surface codes #LTQI #JapanEUWorkshop
Erika Kawakami: The spin-state is used a qubit state, the rydberg states are auxiliary states. T₂=100 s for spin states. 1 qubit gates through ESR; 2-qubit gate using Coulomb interacton #LTQI #JapanEUWorkshop

Shane is fangirling about meeting Rebekah and Kol, the Original vampires, and bragging about not being able to be compelled. Then Bex tells Kol to beat the location of the cure out of him. Lol. Imagine meeting your idols and they beat the shit out of you.
Back to this. "Truth or dare, Elena?"
"Dare." Damn that's brave.
"I dare you to tell Stefan the truth about Damon."
Sweetie, that's truth not dare, but I am here for this.
"Seriously?!" Caroline being there for Stefan again.
Bex is being really childish though
"Being with Damon makes me happy." HSHDFLK YES IT DOES.
"Makes you happy? Clowns make you happy Elena. Dig a little deeper."
Actually, clowns do quite the opposite of making me happy, but to each their own Rebekah. 🙈

From Shabaa to Maarbeh all borders with occupied Golan Heights & with #Jordan are free & under the control of the #Syrian Army.
#ISIS in Yarmouk Bassin is totally defeated eliminated by the Syrian Army & its allies. East of Qunietra Jabbat al-Khashab & Tarnaja r almost over.
More than 13,000 Jihadists of ex-Jabhat alNusra (aka HTS which is the same) have been shipped from the south of Syria to #Idlib (to those ignorants saying "no jihadists in the south).

In #Idlib, there are around 2 million people, including IDP. Thousands of civilians are leaving DAILY the biggest Jihadists stronghold after Tora Bora through a corridor established by #Russia from #Idlib towards the Government-controlled area.

› back to black ‧ taekook au

the one where taehyung is a spy, jungkook is his target, and the world is their playground.
The first time Taehyung goes on a mission, it’s by complete accident.

There’s some sort of chaos outbreak at HQ, and before he knows it, Taehyung--an untrained, unpaid, unsure intern--is swept into a slick black SUV and sent off to an unknown location.
He looks around, not very optimistic at the sight of the other nervous faces in the car. When the vehicle finally stops, the doors are pulled open by a very gruff-looking man, his face streaked with blood and his arm in a rough-looking sling.

Je découvre avec bonheur que Maman a acheté des verres de ce type, ce qui m’amène à vous faire un thread sur

LE CÉLÈBRE VERRE À FACETTES SOVIÉTIQUE
Le verre à facettes (гранёный стакан) a été créé pendant le blocus de Leningrad (1943) par Vera Moukhina, la sculptrice qui a aussi fait « Le travailleur et la kolkhozienne ». D’ailleurs, si on empile 476 verres ça fait la même hauteur !!! #coïncidence???
La valeur de ces verres à facettes soviétiques dépendait du nombre de facettes mais ils faisaient toujours la même contenance, une contenance d’ailleurs idéale pour partager une bouteille de vodka à 3 quand Khrouchtchev en eut interdit la vente par quantité libre

Day 2 of quantum advantage workshop at @InHenriPoincare, featuring Ashley Montanaro (@quantumashley), Juan Bermejo-Vega (myself) and Dominik Hangleiter. #LTQI
We kick off with Ashley Montanaro @quantumashley, giving a tutorial about IQP circuits (IQP = Instantaneous Quantum Polynomial time) and potential for demonstrating superior quantum computational performance. #LQTI
