Scalable phonon-laser arrays with self-organized synchronization
Hugo Molinares, Guillermo Romero, Victor Montenegro +1
Quantum mechanical oscillators operating at frequencies up to the GHz regime have been predicted to support phonon lasing -- self-sustained coherent vibrational motion emerging whe…
Quenching, Fast and Slow: Breaking Kibble-Zurek Universal Scaling by Jumping along Geodesics
Thi Ha Kyaw, Guillermo Romero, Gaurav Saxena
A major drawback of adiabatic quantum computing (AQC) is fulfilling the energy gap constraint, which requires the total evolution time to scale inversely with the square of the min…
Equally entangled multiqubit states
Francisco Albarrán-Arriagada, Guillermo Romero, Juan Carlos Retamal
We present a protocol for generating multiqubit quantum states with translationally invariant pairwise entanglement. Our approach is tailored for digital quantum computers with res…
