Dispersive Qubit Readout with Intrinsic Resonator Reset
M. Jerger, F. Motzoi, Y. Gao +9
A key challenge in quantum computing is speeding up measurement and initialization. Here, we experimentally demonstrate a dispersive measurement method for superconducting qubits t…
Single-shot determination of quantum phases via continuous measurements
Aniket Patra, Lukas F. Buchmann, Felix Motzoi +3
We propose that weak continuous probing may be exploited to determine and define quantum phases of complex many-body systems based on the measurement record alone. We test the resu…
Simple, smooth and fast pulses for dispersive measurements in cavities and quantum networks
Felix Motzoi, Lukas Buchmann, Christian DIckel
We demonstrate a dispersive measurement pulse shaping technique that allows for arbitrarily fast quantum non-demolition, single-quadrature measurements of non-linear systems and un…
Controllability in tunable chains of coupled harmonic oscillators
L. F. Buchmann, K. Mølmer, D. Petrosyan
We prove that temporal control of the strengths of springs connecting harmonic oscillators in a chain provides complete access to all Gaussian states of collective modes.…
Creation and transfer of non-classical states of motion using Rydberg dressing of atoms in a lattice
L F Buchmann, K Mølmer, D Petrosyan
We theoretically investigate the manipulation of the motional states of trapped ground-state atoms using Rydberg dressing via nonresonant laser fields. The forces resulting from Ry…
Complex Squeezing and Force Measurement Beyond the Standard Quantum Limit
L. F. Buchmann, S. Schreppler, J. Kohler +2
A continuous quantum field, such as a propagating beam of light, may be characterized by a squeezing spectrum that is inhomogeneous in frequency. We point out that homodyne detecto…
