Two-qutrit quantum Rabi model is integrable under specific conditions, allowing derivation of ground-state phase diagram with level crossings and superradiant quantum phase transition.
A circular-modulated concatenated continuous driving (CMCCD) protocol for silicon qubits cancels counter-rotating errors via dual modulation and shows higher simulated fidelity plus improved experimental robustness to detuning and Rabi errors compared to standard Rabi or prior CCD drives.
Zero-field resonance protocols identify a hydrogen-related electron-nuclear defect in diamond and enable its nuclear spin qubit control with 1 ms coherence time.
A provable exponential quantum-classical learning separation is established for predicting expectation values of time-evolved quantum states under unknown low-intersection Hamiltonians, assuming BQP ⊄ P/poly.
Resonant energy transfer in dense spin systems is limited by the pair-detuning width of Ising interactions, rescaling relaxation times from r^6 to r^{4.5} in 3D and from r^4 to r^3 in 2D.
In an N-qubit network with one conserved excitation, a single transition amplitude determines positivity and complete positivity of subsystem propagators, links them to excitation flow and Fisher information, and reveals an unvisited band of states inside the positivity domain.
Moire superlattices naturally create tunable arrays of artificial atoms with uniform optical transition energies suitable for quantum optics applications across many wavelengths.
Proposes entangled electron qubits on helium in a double-well trap as a quantum sensor concept for enhanced sensitivity in particle physics.
