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

Now, Eleni Diamanti on Practical Secure Quantum Communications #JapanEUWorkshop #LTQI
Eleni Diamanti: The current solution to secure network links: Symmetric + Asymmetric cryptography. Recent development to fight the threat of quantum computers: postquantum cryptography. Quantum cryptography offers the advantage to be future proof #LTQI
Eleni Diamanti: REal security will have to combine the the use of classical and quantum cryptography. nature.com/articles/nphys…

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
