The Structure of Quantum Questions
Yang Yu, Philip Goyal
In classical physics, a single measurement can in principle reveal the state of a system. However, quantum theory permits numerous non-equivalent measurements on a physical system,…
Principle of Information Increase: An Operational Perspective of Information Gain in the Foundations of Quantum Theory
Yang Yu, Philip Goyal
A measurement performed on a quantum system is an act of gaining information about its state, a view that is widespread in practical and foundational work in quantum theory. Howeve…
Engineering phonon-phonon interactions in multimode circuit quantum acousto-dynamics
Uwe von Lüpke, Ines C. Rodrigues, Yu Yang +2
In recent years, remarkable progress has been made towards encoding and processing quantum information in the large Hilbert space of bosonic modes. Mechanical resonators are of gre…
Schrödinger cat states of a 16-microgram mechanical oscillator
Marius Bild, Matteo Fadel, Yu Yang +4
The superposition principle is one of the most fundamental principles of quantum mechanics. According to the Schrödinger equation, a physical system can be in any linear combinatio…
Macroscopic quantum test with bulk acoustic wave resonators
Björn Schrinski, Yu Yang, Uwe von Lüpke +5
Recently, solid-state mechanical resonators have become a platform for demonstrating non-classical behavior of systems involving a truly macroscopic number of particles. Here, we p…
Untwining multiple parameters at the exclusive zero-coincidence points with quantum control
Yu Yang, Federico Belliardo, Vittorio Giovannetti +1
In this paper we address a special case of "sloppy" quantum estimation procedures which happens in the presence of intertwined parameters. A collection of parameters are said to be…
Multiparameter simultaneous optimal estimation with an SU(2) coding unitary evolution
Yu Yang, Shihao Ru, Min An +4
In a ubiquitous dynamics, achieving the simultaneous optimal estimation of multiple parameters is significant but difficult. Using quantum control to optimize this …
Parity measurement in the strong dispersive regime of circuit quantum acoustodynamics
Uwe von Lüpke, Yu Yang, Marius Bild +3
Mechanical resonators are emerging as an important new platform for quantum science and technologies. A large number of proposals for using them to store, process, and transduce qu…
Quantum state transfer between two photons with polarization and orbital angular momentum via quantum teleportation technology
Shihao Ru, Min An, Yu Yang +5
Quantum teleportation is a useful quantum information technology to transmit quantum states between different degrees of freedom. We here report a quantum state transfer experiment…
Exclusive Hong-Ou-Mandel zero-coincidence point
Yu Yang, Luping Xu, Vittorio Giovannetti
A generalized multi-parameter Hong-Ou-Mandel interferometer is presented which extends the conventional "Mandel dip" configuration to the case where a symmetric biphoton source is…
Two-parameter Hong-Ou-Mandel dip
Yu Yang, Luping Xu, Vittorio Giovannetti
A modification of the standard Hong-Ou-Mandel interferometer is proposed which allows one to replicate the celebrated coincidence dip in the case of two-independent delay parameter…
