Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

May 8, 2024
Author(s)
Noah Schlossberger, Nik Prajapati, Samuel Berweger, Andrew Rotunno, Aly Artusio-Glimpse, Abrar Sheikh, Eric Norrgard, Christopher L. Holloway, Stephen Eckel
Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields

We successfully demonstrated polarization entanglement distribution and classical time synchronization using a high-accuracy precision time protocol between two quantum nodes located 250 meters apart using a single fiber simultaneously carrying both

Constraints on Gaussian Error Channels and Measurements for Quantum Communication

April 10, 2023
Author(s)
Alexander T. Kwiatkowski, Ezad Shojaee, Sristy Agrawal, Akira Kyle, Curtis Rau, Scott Glancy, Emanuel Knill
Joint Gaussian measurements of two quantum systems are important for quantum communication between remote parties and are often used in continuous-variable teleportation or entanglement-swapping protocols. Many of the errors in real-world implementations

Author(s)
Ivan Burenkov, Alexandra Semionova, FNU Hala, Thomas Gerrits, Anouar Rahmouni, DJ Anand, Ya-Shian Li-Baboud, Oliver T. Slattery, Abdella Battou, Sergey Polyakov
We investigate the coexistence of clock synchronization protocols with quantum signals in a common single-mode optical fiber. By measuring optical noise between 1500 nm to 1620 nm we demonstrate a potential for up to 100 quantum DWDM channels coexisting

Oliver T. Slattery, Adam Black
Quantum networks [1] bear the promise of one day enabling diverse applications such as secure communications, distributed quantum computing, distributed sensing, and time distribution, in addition to other applications not yet identified. In recent years

Author(s)
Anouar Rahmouni, Thomas Gerrits, Paulina Kuo, Dileep Reddy, Lijun Ma, Xiao Tang, Oliver T. Slattery
A quantum network will consist of many physically separated nodes connected by quantum communication channels that distribute entanglement between them. Such nodes will require mechanisms for the generation, routing, and measurement of quantum states to

Author(s)
Anouar Rahmouni, Lijun Ma, Xiao Tang, Thomas Gerrits, Lutong Cai, Qing Li, Oliver T. Slattery
Entangled photon sources are fundamental building blocks for quantum communication and quantum networks. Recently, silicon carbide emerged as a promising material for integrated quantum devices since it is CMOS compatible with favorable mechanical

Author(s)
Jabir Marakkarakath Vadakkepurayil, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
We introduce new practical modulation schemes inspired by the quantum measurement. We experimentally show that our quantum-enabled communication system optimizes the combined resource efficiency (CRE) beyond the classical, shot-noise-limited CRE.

Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

Author(s)
Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal

Author(s)
Ivan Burenkov, Jabir Marakkarakath Vadakkepurayil, Sergey Polyakov
Communication is an integral part of human life. Today, optical pulses are the preferred information carriers for long-distance communication. The exponential growth in data leads to a "capacity crunch" in the underlying physical systems. One of the
