New preprint just in time for the #APSMarch meeting: arxiv.org/abs/2403.00285
With @sandokokosen, @JonasBylander2, and the experimental team @wacqt_sweden @chalmersuniv @QTL_Chalmers (and @VTTFinland through @OpenSuperQPlus), we characterize crosstalk on our quantum processors.

New experimental results out today with collaborators from @QTL_Chalmers! We measure the long sought-after cubic phase state that is obtained by applying the cubic Hamiltonian x³ to an initial squeezed state, by engineering the cubic gate explicitly! scirate.com/arxiv/2308.15320 (1/7)

Refrigerators are very useful. What about quantum refrigerators? Can they be useful? We built one @QTL_Chalmers that is!

ConScience and @QTL_Chalmers are working on scaled qubit production to 4-inch wafer to facilitate commercial adoption of quantum technologies.
Here we present our first successful 4-inch Qubit wafer (proprietary designs blurred).

New preprint out today: arxiv.org/abs/2212.12079. At @QTL_Chalmers @wacqt_sweden @chalmersuniv, we realize a collection of photon-number-selective, simultaneous photon addition operations on a bosonic mode, a microwave cavity, assisted by a superconducting qubit.

New preprint out today: arxiv.org/abs/2207.02938. At @QTL_Chalmers @wacqt_sweden @chalmersuniv we demonstrate, using superconducting qubits, a family of three-qubit gates that we proposed last year (doi.org/10.1103/PRXQuantum.2…). An exciting software upgrade for quantum computers!
