Fundamental Limits on Subwavelength Range Resolution
Andrew N. Jordan, John C. Howell
We establish fundamental bounds on subwavelength resolution for the radar ranging problem, ``super radar''. Information theoretical metrics are applied to probe the resolution limi…
A quantum Stirling heat engine operating in finite time
Debmalya Das, George Thomas, Andrew N. Jordan
In a quantum Stirling heat engine, the heat exchanged with two thermal baths is partly utilized for performing work by redistributing the energy levels of the working substance. We…
Supergrowth and sub-wavelength object imaging
Tathagata Karmakar, Abhishek Chakraborty, A. Nick Vamivakas +1
We further develop the concept of supergrowth [Jordan, Quantum Stud.: Math. Found. , 285-292 (2020)], a phenomenon complementary to superoscillation, defined as the loc…
Probabilistic Unitary Formulation of Open Quantum System Dynamics
Le Hu, Andrew N. Jordan
We show that all non-relativistic quantum processes, whether open or closed, are either unitary or probabilistic unitary, i.e., probabilistic combination of unitary evolutions. Thi…
Beyond Superoscillation: General Theory of Approximation with Bandlimited Functions
Tathagata Karmakar, Andrew N. Jordan
We give a general strategy to construct superoscillating/growing functions using an orthogonal polynomial expansion of a bandlimited function. The degree of superoscillation/growth…
Reservoir-Free Decoherence in Flying Qubits
Nicolò Piccione, Léa Bresque, Andrew N. Jordan +2
An effective time-dependent Hamiltonian can be implemented by making a quantum system fly through an inhomogeneous potential, realizing, for example, a quantum gate on its internal…
