Metrological Advantages in Seeded and Lossy Nonlinear Interferometers
Jasper Kranias, Guillaume Thekkadath, Khabat Heshami +1
The quantum Fisher information (QFI) bounds the sensitivity of a quantum measurement, heralding the conditions for quantum advantages when compared with classical strategies. Here,…
Seeding Gaussian boson samplers with single photons for enhanced state generation
Valerio Crescimanna, Aaron Z. Goldberg, Khabat Heshami
Non-Gaussian quantum states are crucial to fault-tolerant quantum computation with continuous-variable systems. Usually, generation of such states involves trade-offs between succe…
Evading noise in multiparameter quantum metrology with indefinite causal order
A. Z. Goldberg, L. L. Sanchez-Soto, K. Heshami
Quantum theory allows the traversing of multiple channels in a superposition of different orders. When the order in which the channels are traversed is controlled by an auxiliary q…
Covariant operator bases for continuous variables
A. Z. Goldberg, A. B. Klimov, G. Leuchs +1
Coherent-state representations are a standard tool to deal with continuous-variable systems, as they allow one to efficiently visualize quantum states in phase space. Here, we work…
Teleamplification on the Borealis boson-sampling device
Aaron Z. Goldberg, Khabat Heshami
A recent theoretical proposal for teleamplification requires preparation of Fock states, programmable interferometers, and photon-number resolving detectors to herald the teleampli…
Quantum control of Rydberg atoms for mesoscopic-scale quantum state and circuit preparation
Valerio Crescimanna, Jacob Taylor, Aaron Z. Goldberg +1
Individually trapped Rydberg atoms show significant promise as a platform for scalable quantum simulation and for development of programmable quantum computers. In particular, the…
High-dimensional Encoding in the Round-Robin Differential-Phase-Shift Protocol
Mikka Stasiuk, Felix Hufnagel, Xiaoqin Gao +4
In quantum key distribution (QKD), protocols are tailored to adopt desirable experimental attributes, including high key rates, operation in high noise levels, and practical securi…
Measuring the quadrature coherence scale on a cloud quantum computer
Aaron Z. Goldberg, Guillaume S. Thekkadath, Khabat Heshami
Coherence underlies quantum phenomena, yet it is manifest in classical theories; delineating coherence's role is a fickle business. The quadrature coherence scale (QCS) was invente…
Efficient lineshape estimation by ghost spectroscopy
Ilaria Gianani, Luis L. Sanchez Soto, Aaron Z. Goldberg +1
Recovering the original spectral lineshapes from data obtained by instruments with extended transmission profiles is a basic tenet in spectroscopy. By using the moments of the meas…
