IEQNET consists of multiple sites that are geographically dispersed in the Chicago metropolitan area. Each site has one or more quantum nodes (Qnodes) representing the communication parties in a quantum network. Q-nodes generate or measure quantum signals such as entangled photons and communicate the results via standard, classical, means. The entangled photons in IEQNET nodes are generated at multiple wavelengths, and are selectively distributed to the desired users via optical switches. Here we describe the network architecture of IEQNET, including the Internet-inspired layered hierarchy that leverages software-defined-networking (SDN) technology to perform traditional wavelength routing and assignment between the Q-nodes. Specifically, SDN decouples the control and data planes, with the control plane being entirely classical. Issues associated with synchronization, calibration, network monitoring, and scheduling will be discussed. An important goal of IEQNET is demonstrating the extent to which the control plane can coexist with the data plane using the same fiber lines. This goal is furthered by the use of tunable narrow-band optical filtering at the receivers and, at least in some cases, a wide wavelength separation between the quantum and classical channels. We envision IEQNET to aid in developing robust and practical quantum networks by demonstrating metro-scale quantum communication tasks such as entanglement distribution and quantum-state teleportation.", "doi": "10.1117/12.2588007", "publisher": "Society of Photo-optical Instrumentation Engineers", "publication_date": "2021-04-12" }, { "id": "authors:t33j9-b2223", "collection": "authors", "collection_id": "t33j9-b2223", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180816-101633176", "type": "book_section", "title": "Precision Timing Detectors with Cadmium Telluride Sensors", "book_title": "Proceedings of International Conference on Technology and Instrumentation in Particle Physics 2017", "author": [ { "family_name": "Bornheim", "given_name": "Adi", "orcid": "0000-0002-0128-0871", "clpid": "Bornheim-A" }, { "family_name": "Mao", "given_name": "Jiajing", "clpid": "Mao-Jiajing" }, { "family_name": "Mangu", "given_name": "Aashrita", "clpid": "Mangu-A" }, { "family_name": "Pena", "given_name": "Cristian", "clpid": "Pena-C" }, { "family_name": "Spiropulu", "given_name": "Maria", "orcid": "0000-0001-8172-7081", "clpid": "Spiropulu-M" }, { "family_name": "Xie", "given_name": "Si", "orcid": "0000-0003-2509-5731", "clpid": "Xie-Si" }, { "family_name": "Zhang", "given_name": "Zhicai", "orcid": "0000-0002-1630-0986", "clpid": "Zhang-Zhicai" } ], "contributor": [ { "family_name": "Liu", "given_name": "Zhen-An", "clpid": "Liu-Zhen-An" } ], "abstract": "Precision timing detectors for high energy physics experiments with temporal resolutions of a few 10 ps are of pivotal importance to master the challenges posed by the highest energy particle accelerators. Calorimetric timing measurements have been a focus of recent research, enabled by exploiting the temporal coherence of electromagnetic showers. Scintillating crystals with high light yield as well as silicon sensors are viable sensitive materials for sampling calorimeters. Silicon sensors have very high efficiency for charged particles. However, their sensitivity to photons, which comprise a large fraction of the electromagnetic shower, is limited. A large fraction of the energy in an electromagnetic shower is carried by photons. To enhance the efficiency of detecting photons, materials with higher atomic numbers than silicon are preferable. In this paper we present test beam measurements with a Cadmium-Telluride sensor as the active element of a secondary emission calorimeter with focus on the timing performance of the detector. A Schottky type Cadmium-Telluride sensor with an active area of 1 cm2 and a thickness of 1 mm is used in an arrangement with tungsten and lead absorbers. Measurements are performed with electron beams in the energy range from 2 GeV to 200 GeV. A timing resolution of 20 ps is achieved under the best conditions.", "doi": "10.1007/978-981-13-1316-5_10", "isbn": "978-981-13-1315-8", "publisher": "Springer", "place_of_publication": "Singapore", "publication_date": "2018-08-08", "pages": "56-60" }, { "id": "authors:m22b3-pjp28", "collection": "authors", "collection_id": "m22b3-pjp28", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20181126-154925497", "type": "book_section", "title": "Precision Timing Detectors with Cadmium Telluride Sensors", "book_title": "2017 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC)", "author": [ { "family_name": "Anderson", "given_name": "Dustin", "clpid": "Anderson-D" }, { "family_name": "Bornheim", "given_name": "Adi", "orcid": "0000-0002-0128-0871", "clpid": "Bornheim-A" }, { "family_name": "Mangu", "given_name": "Aashrita", "clpid": "Mangu-A" }, { "family_name": "Mao", "given_name": "Jiajing", "clpid": "Mao-Jiajing" }, { "family_name": "Pena", "given_name": "Cristian", "clpid": "Pena-C" }, { "family_name": "Spiropulu", "given_name": "Maria", "orcid": "0000-0001-8172-7081", "clpid": "Spiropulu-M" }, { "family_name": "Xie", "given_name": "Si", "orcid": "0000-0003-2509-5731", "clpid": "Xie-Si" }, { "family_name": "Zhang", "given_name": "Zhicai", "orcid": "0000-0002-1630-0986", "clpid": "Zhang-Zhicai" } ], "abstract": "Precision timing properties of high energy physics detectors in high luminosity colliders has become an important requirement for the success of particle detection, of which new calorimeter with timing precision of few tens of ps is the main interest.
