Quantum repeaters based on concatenated bosonic and discrete-variable quantum codes
Filip Rozpędek, Kyungjoo Noh, Qian Xu +2
We propose an architecture of quantum-error-correction-based quantum repeaters that combines techniques used in discrete- and continuous-variable quantum information. Specifically,…
Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer
J. Eli Bourassa, Rafael N. Alexander, Michael Vasmer +10
Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far…
High-Purity Pulsed Squeezing Generation with Integrated Photonics
Chaohan Cui, Christos N. Gagatsos, Saikat Guha +1
Squeezed light has evolved into a powerful tool for quantum technology, ranging from quantum enhanced sensing and quantum state engineering based on partial post-selection techniqu…
High-dimensional Frequency-Encoded Quantum Information Processing with Passive Photonics and Time-Resolving Detection
Chaohan Cui, Kaushik P. Seshadreesan, Saikat Guha +1
In this Letter, we propose a new approach to process high-dimensional quantum information encoded in a photon frequency domain. In contrast to previous approaches based on nonlinea…
Entanglement generation in a quantum network at distance-independent rate
Ashlesha Patil, Mihir Pant, Dirk Englund +2
We develop a protocol for entanglement generation in the quantum internet that allows a repeater node to use -qubit Greenberger-Horne-Zeilinger (GHZ) projective measurements tha…
Entanglement Enhanced Estimation of a Parameter Embedded in Multiple Phases
Michael R. Grace, Christos N. Gagatsos, Saikat Guha
Quantum-enhanced sensing promises to improve the performance of sensing tasks using non-classical probes and measurements that require far fewer scene-modulated photons than the be…
Quantum-Enhanced Fiber-Optic Gyroscopes Using Quadrature Squeezing and Continuous Variable Entanglement
Michael R Grace, Christos N. Gagatsos, Quntao Zhuang +1
We analyze a fiber-optic gyroscope design enhanced by the injection of quantum-optical squeezed vacuum into a fiber-based Sagnac interferometer. In the presence of fiber loss, we c…
Belief Propagation with Quantum Messages for Quantum-Enhanced Classical Communications
Narayanan Rengaswamy, Kaushik P. Seshadreesan, Saikat Guha +1
For space-based laser communications, when the mean photon number per received optical pulse is much smaller than one, there is a large gap between communications capacity achievab…
Programming the Kennedy Receiver for Capacity Maximization versus Minimizing One-shot Error Probability
Rahul Bhadani, Michael Grace, Ivan B. Djordjevic +2
We find the capacity attained by the Kennedy receiver for coherent-state BPSK when the symbol prior p and pre-detection displacement are optimized. The optimal displacement is diff…
Infinite-fold enhancement in communications capacity using pre-shared entanglement
Saikat Guha, Quntao Zhuang, Boulat Bash
Pre-shared entanglement can significantly boost communication rates in the regime of high thermal noise, and a low-brightness transmitter. In this regime, the ratio between the ent…
Development of Quantum InterConnects for Next-Generation Information Technologies
David Awschalom, Karl K. Berggren, Hannes Bernien +32
Just as classical information technology rests on a foundation built of interconnected information-processing systems, quantum information technology (QIT) must do the same. A crit…
