Now, Yoshiro Takahashi from @KyotoU_News on Advanced quantum simulator with novel
spin and orbital degrees of freedom #LTQI
@KyotoU_News Yoshihiro Takahashi: With ¹⁷³Yb nuclear spins, we have a SU(6) Fermi-Hubbard model. They observe formation of SU(6) Mott insulator.
#LTQI #JapanEUWorkshop
@KyotoU_News Yoshihiro Takahashi ’s next traget: SU(6) quantum magnetism. A difficulty is measuring spin correlation, which is achieved through singlet-triplet oscillation compined with photo association #LTQI #JapanEUWorkshop
@KyotoU_News Yoshihiro Takahashi has actually oberved singlet-triplet oscillation of SU(4) fermions
#LTQI #JapanEUworkshop
@KyotoU_News Yoshihiro Takahashi: SU(6) induces complicatons, the STO signal includes 3 frequency components, but the experiment behaves as expected. #LTQI #JapanEUWorkshop
@KyotoU_News Yoshihior Takahashi saw SU(6) antiferromagnetic correlation in an isotropic lattice #LTQI #JapanEUWorkshop
@KyotoU_News Yoshihiro Takahashi also used a ¹⁷¹Yb gas as a Kondo simulator. #JapanEUWorkshop #LTQI

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

@EricHolthaus Now let's talk about solutions. First of all, slow the bleeding. QUIT CLOSING #NUCLEAR POWER PLANTS. Oyster Creek shutting down is like taking a baseball bat to over 5 Ivanpah solar plants; it produced ~5400 GWh zero-GHG per year vs Ivanpah's 990 GWh.
@EricHolthaus The replacement power isn't coming from solar and wind, guys. It's coming from natural gas and coal. Solar and wind can't compete with the kind of reliable capacity factor Oyster Creek delivered 24/7.
@EricHolthaus #nuclear power stations that are "unprofitable" are largely so because of cheap natural gas + renewables forcing nuke operators to deal with negative electricity prices. atomicinsights.com/why-cant-exist… NG won't be cheap forever, but #climatechange will continue getting worse.

Six #nuclear reactors closed since 2013. By my count, up to 23 more reactors may retire w/o policy or market conditions improving: 21.6 GW = ~1/5th of US fleet, 4% of US #electricity--and crucially, 12% of emissions-free generation.

So what's killing nuclear power in the U.S.?
In a new @MIT CEEPR paper -- 1 part #energy #economics & 1 part film noir murder mystery! -- I provide the 1st empirical estimates of what's driving down #electricity market prices & killing profitability of 19 #nuclear power plants across @pjminterconnect ceepr.mit.edu/publications/w…
You can read a short policy brief summarizing the paper & key conclusions @MIT CEEPR here: ceepr.mit.edu/files/papers/2…
