Quantum 2.0 Conference and Exhibition

13 June 2022 – 16 June 2022 Encore Boston Harbor, Everett, Massachusetts United States

Stimulating and facilitating the development of quantum information science and technology.

Quantum 2.0 is a new OSA conference focusing on the development and use of many-body quantum superposition, entanglement, and measurement to advance science and technology. Examples are quantum computing and simulation, quantum communications, and quantum sensing. New resulting technologies will potentially go far beyond the (quantum 1.0) capabilities offered by systems without the conceptual need for large-scale superposition or entanglement, examples of which are conventional semiconductor electronics, laser-based communication systems and magnetic-resonance medical imagers.

New Material Systems for Superconducting Qubits

Building large, useful quantum systems based on transmon qubits will require significant improvements in qubit relaxation and coherence times, which are orders of magnitude shorter than limits imposed by bulk properties of the constituent materials. However, significant improvements in the lifetime of planar transmon qubits have remained elusive for several years. We have fabricated planar transmon qubits that have both lifetimes and coherence times exceeding 0.3 milliseconds by replacing niobium with tantalum in the device. Following this discovery, we have parametrized the remaining sources of loss in state-of-the-art devices using systematic measurements of the dependence of loss on temperature, power, and geometry. This parametrization, complemented by direct materials characterization, allows for rational, directed improvement of superconducting qubits.

From Multi-Photon Entanglement to Quantum Computational Advantage

By developing high-performance quantum light sources, the multi-photon interference has been scaled up to implement boson sampling with up to 76 photons out of a 100-mode interferometer, which yields a Hilbert state space dimension of 1030 and a rate that is 1014 faster than using the state-of-the-art simulation strategy on supercomputers. Such a demonstration of quantum computational advantage is a much-anticipated milestone for quantum computing. The special-purpose photonic platform will be further used to investigate practical applications linked to the Gaussian boson sampling, such as graph optimization and quantum machine learning.

John Preskill

California Institute of Technology

Making Predictions in a Quantum World

I will review an experimentally feasible procedure for converting a quantum state into a succinct classical description of the state, its classical shadow. Classical shadows can be applied to predict efficiently many properties of interest, including expectation values of local observables and few-body correlation functions. Efficient classical machine learning algorithms using classical shadows can address quantum many-body problems such as classifying quantum phases of matter. I will also explain how experiments that exploit quantum memory can learn properties of a quantum system far more efficiently than conventional experiments.

Innovation Potentials of Quantum Technology of 2nd Generation for Optics and Photonics

Starting from the requirements in microscopy, health care, industrial metrology and optical lithography we analyze the potential of a range of quantum optical concepts in comparison to the classical state of the art. In particular we consider ghost imaging, imaging with undetected photons, the use of entangled photons for 2 photon imaging and optical coherence microscopy, NOON state metrology and lithography, antibunching microscopy and NVC magnetic field measurements.

Programmable Quantum Simulators with Atoms and Ions

Quantum simulation aims at `solving' complex quantum many-body problems efficiently and with controlled errors on quantum devices. Here we discuss quantum simulation from the perspective of programmable analog quantum simulators, as realized in present cold atom and ion experiments, where the unique features are scalability to large particle numbers and programmability. The focus of this talk is to report work from a theory-experiment collaboration with a programmable trapped ion platform with up to fifty qubits/spins, with the goal to develop and demonstrate a toolbox of quantum protocols, addressing questions from fundamental quantum science to application as quantum technology. Examples include the demonstration of variational quantum algorithms preparing many-body ground states, and measurement protocols revealing the entanglement structure of the many-body wavefunction, e.g. as tomography of the entanglement Hamiltonian. In addition, we demonstrate `optimal' quantum metrology with variational quantum circuits, where quantum simulators act as `programmable quantum sensors'. Finally, we address the problem of verification of quantum simulators via Hamiltonian and Liouvillian learning as an experimental protocol, i.e. we `learn' the operator structure of both the many-body Hamiltonian and Lindbladian characterizing (Markovian) decoherence.

Technology Showcase: Scalable Control Stacks for Quantum Networks

Wednesday, 15 June 15:30 – 15:50

A quantum internet aims to send quantum information, e.g., qubits, from one point to another over a large-distance network and enables quantum-communication applications that are not possible with the internet today. Current efforts by academia and industry investigate connecting computational quantum nodes via quantum links as well as classical links which are required for low-latency exchange of classical information. Thus, building such networks is a multifold challenge, not only including the development of quantum devices, but also the control hardware architecture and network software stack. Qblox supports this with distributed, ultralow-noise, and interconnected control stacks. We introduce the Cluster system which incorporates processors capable of sequencing pulses, their parameters, and exchanging measurement results in real time. The Cluster supports many qubit platforms with its wide frequency range from DC to 18.5 GHz while occupying less volume than 1 liter per controlled qubit. This full-stack approach opens a fast track for node optimizations and many-node scaling efforts towards realizing a quantum internet.

Movie Night: Quantum Shorts Film Festival
