Experimental evidence that a photon can spend a negative amount of time in an atom cloud
Daniela Angulo, Kyle Thompson, Vida-Michelle Nixon +3
When a pulse of light traverses a material, it incurs a time delay referred to as the group delay. Should the group delay experienced by photons be attributed to the time they spen…
How much time does a photon spend as an atomic excitation before being transmitted?
Kyle Thompson, Kehui Li, Daniela Angulo +5
When a single photon traverses a cloud of 2-level atoms, the average time it spends as an atomic excitation -- as measured by weakly probing the atoms -- can be shown to be the spo…
Measuring the time atoms spend in the excited state due to a photon they don't absorb
Josiah Sinclair, Daniela Angulo, Kyle Thompson +3
When a resonant photon traverses a sample of absorbing atoms, how much time do atoms spend in the excited state? Does the answer depend on whether the photon is ultimately absorbed…
Observation of a large, resonant, cross-Kerr nonlinearity in a free-space Rydberg medium
Josiah Sinclair, Daniela Angulo, Noah Lupu-Gladstein +2
We report the experimental observation of a cross-Kerr nonlinearity in a free-space medium based on resonantly-excited, interacting Rydberg atoms and electromagnetically induced tr…
Single plane minimal tomography of double slit qubits
Edwin C. Chaparro Sogamoso, D. Angulo, K. M. Fonseca-Romero
The determination of the density matrix of an ensemble of identically prepared quantum systems by performing a series of measurements, known as quantum tomography, is minimal when…
