How Real is Incomputability in Physics?
José Manuel Agüero Trejo, Cristian S. Calude, Michael J. Dinneen +4
A physical system is determined by a finite set of initial conditions and "laws" represented by equations. The system is computable if we can solve the equations in all instances u…
Passive microwave circulation on a superconducting chip
Arkady Fedorov, N. Pradeep Kumar, Dat Thanh Le +3
Building large-scale superconducting quantum circuits will require miniaturisation and integration of supporting devices including microwave circulators, which are currently bulky,…
Passive superconducting circulator on a chip
Rohit Navarathna, Dat Thanh Le, Andrés Rosario Hamann +3
An on-chip microwave circulator that is compatible with superconducting devices is a key element for scale-up of superconducting circuits. Previous approaches to integrating circul…
Bound states in microwave QED: Crossover from waveguide to cavity regime
N. Pradeep Kumar, Andrès Rosario Hamann, Rohit Navarathna +3
Light-matter interaction at the single-quantum level is the heart of many regimes of high fundamental importance to modern quantum technologies. Strong interaction of a qubit with…
Neural networks for on-the-fly single-shot state classification
Rohit Navarathna, Tyler Jones, Tina Moghaddam +5
Neural networks have proven to be efficient for a number of practical applications ranging from image recognition to identifying phase transitions in quantum physics models. In thi…
Operating a passive on-chip superconducting circulator: device control and quasiparticle effects
Dat Thanh Le, Clemens Muller, Rohit Navarathna +2
Microwave circulators play an important role in quantum technology based on superconducting circuits. The conventional circulator design, which employs ferrite materials, is bulky…
Measuring effective temperatures of qubits using correlations
Anatoly Kulikov, Rohit Navarathna, Arkady Fedorov
Initialization of a qubit in a pure state is a prerequisite for quantum computer operation. Qubits are commonly initialized by cooling to their ground states through passive therma…
An optomechanical platform with a 3-dimensional waveguide cavity
Bindu Gunupudi, Soumya Ranjan Das, Rohit Navarathna +3
At low temperatures, microwave cavities are often preferred for the readout and control of a variety of systems. In this paper, we present design and measurements on an optomechani…
