Quantum-Classical Separation in Bounded-Resource Tasks Arising from Measurement Contextuality
Shashwat Kumar, Eliott Rosenberg, Alejandro Grajales Dau +280
The prevailing view is that quantum phenomena can be harnessed to tackle certain problems beyond the reach of classical approaches. Quantifying this capability as a quantum-classic…
Probing Environmental Spin Polarization with Superconducting Flux Qubits
T. Lanting, M. H. Amin, C. Baron +6
We present measurements of the dynamics of a polarized magnetic environment coupled to the flux degree of freedom of rf-SQUID flux qubits. The qubits are used as both sources of po…
A blueprint for demonstrating quantum supremacy with superconducting qubits
C. Neill, P. Roushan, K. Kechedzhi +25
Fundamental questions in chemistry and physics may never be answered due to the exponential complexity of the underlying quantum phenomena. A desire to overcome this challenge has…
Quantum dynamics of a domain wall in the presence of dephasing
Claudio Castelnovo, Mark I. Dykman, Vadim N. Smelyanskiy +2
We compare quantum dynamics in the presence of Markovian dephasing for a particle hopping on a chain and for an Ising domain wall whose motion leaves behind a string of flipped spi…
