What is the Fastest Speed at which a Single Electron Can Be Detected?
Deepak S. Rao, Thomas Szkopek, HongWen Jiang +1
Electrometers measure electric charge, but there must be a fundamental speed limit to measuring one electric charge. Since there are no dimensional inputs to this question, the ans…
Threshold Error Penalty for Fault Tolerant Computation with Nearest Neighbour Communication
T. Szkopek, P. O. Boykin, H. Fan +5
The error threshold for fault tolerant quantum computation with concatenated encoding of qubits is penalized by internal communication overhead. Many quantum computation proposals…
Single photo-electron trapping, storage, and detection in a one-electron quantum dot
Deepak Sethu Rao, Thomas Szkopek, Hans Daniel Robinson +2
There has been considerable progress in electro-statically emptying, and re-filling, quantum dots with individual electrons. Typically the quantum dot is defined by electrostatic g…
Optimal two-qubit quantum circuits using exchange interactions
Heng Fan, Vwani Roychowdhury, Thomas Szkopek
The Heisenberg exchange interaction is a natural method to implement non-local (i.e., multi-qubit) quantum gates in quantum information processing. We consider quantum circuits com…
Eigenvalue Estimation of Differential Operators
Thomas Szkopek, Vwani Roychowdhury, Eli Yablonovitch +1
We demonstrate how linear differential operators could be emulated by a quantum processor, should one ever be built, using the Abrams-Lloyd algorithm. Given a linear differential o…
