In-Situ absolute phase detection of a microwave field via incoherent fluorescence
George C. Cardoso, Prabhakar Pradhan, Jacob Morzinski +1
Measuring the amplitude and the absolute phase of a monochromatic microwave field at a specific point of space and time has many potential applications, including precise qubit rot…
Two-dimensional Nanolithography Using Atom Interferometry
A. Gangat, P. Pradhan, G. Pati +1
We propose a novel scheme for the lithography of arbitrary, two-dimensional nanostructures via matter-wave interference. The required quantum control is provided by a pi/2-pi-pi/2…
Effects of the Bloch-Siegert Oscillation on the Precision of Qubit Rotations: Direct Two-Level vs. Off-Resonant Raman Excitation
Prabhakar Pradhan, George C. Cardoso, Jacob Morzinski +1
In a direct two-level qubit system, when the Rabi frequency is comparable to the resonance frequency, the rotating wave approximation is not appropriate. In this case, the Rabi osc…
Wavelength Teleportation via Distant Quantum Entanglement
M. S. Shahriar, P. Pradhan, V. Gopal +2
Recently, we have shown theoretically [1] as well as experimentally [2] how the phase of an electromagnetic field can be determined by measuring the population of either of the two…
Continuously Guided Atomic Interferometry Using a Single-Zone Optical Excitation: Theoretical Analysis
M. S. Shahriar, M. Jheeta, Y. Tan +2
In an atomic interferometer, the phase shift due to rotation is proportional to the area enclosed by the split components of the atom. However, this model is unclear for an atomic…
Fundamental limitation on qubit operations due to the Bloch-Siegert Oscillation
M. S. Shahriar, Prabhakar Pradhan
We show that if the Rabi frequency is comparable to the Bohr frequency so that the rotating wave approximation is inappropriate, an extra oscillation is present with the Rabi oscil…
