BOSTON, Mass. — Quantum technology has seen major advancements in computing, communications and sensing — areas that rely heavily on optics and photonics. Public and private sectors are making significant investments in these architectures, which means big opportunities for the optics and photonics community. Optica’s Quantum 2.0 conference will be presented in a hybrid format, 13–16 June 2022. This approach will accommodate speakers and attendees from across the globe with in-person and on-demand content.

With five days of technical sessions, the conference will feature technical presentations by invited speakers and contributed talks, plus special events and six distinguished plenary keynote speakers. The exhibition will include industry-focused sessions and companies showcasing market-ready technologies across areas of quantum science and applications.

“The plenary sessions are one of the most highly anticipated components of Quantum 2.0, and we are particularly excited to present this year’s line-up of visionaries,” said Michael Raymer, University of Oregon, United States, Co-Chair. “Each year, we select individuals who inspire us by making great strides in the development of mature quantum technologies that will allow us to build Quantum 2.0 systems capable of quantum advantage.”

“The conference will offer the opportunity to interact with experts in the field, form partnerships and discuss new technologies in the QIST community is a main attraction of the conference,” said Christopher Monroe, Duke University, United States, Co-Chair. “Attendees will have the opportunity to interact and discover common ground, and potentially build collaborations leading to new concepts or development opportunities.”

Show Floor Programming
Quantum 2.0 will present a show floor program that will include six programs focused on technical challenges and exploring broader challenges facing the nascent quantum 2.0 industrial community. The show floor programs will cover the prospects and challenges facing quantum sensors, quantum networks, quantum internet and quantum computing. The session on quantum computing will focus on the challenges of photonics in quantum computing looking at both optical approaches to quantum computing and the need for photonics in quantum computing to interconnect individual quantum processor units. The rapidly evolving quantum industry has challenges from workforce development to creating a robust quantum-related supply chain, to what it takes to create a new start-up company in the quantum industry.  

Plenary Keynote Speakers
Nathalie de Leon, Princeton University, USA
Presentation: 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.

Presentation: 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, USA
Presentation: Making Predictions in a Quantum World
The presentation 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. Preskill will also explain how experiments that exploit quantum memory can learn properties of a quantum system far more efficiently than conventional experiments.

Christine Silberhorn, Paderborn University, USA
Presentation: Photonic Quantum Information Processing
High-dimensional quantum systems based on single and multi-photon states offer an attractive platform for quantum information and technology applications. Here we will discuss the challenges, potential and current progress for the experimental implementation of large photonic systems for scalable quantum information processing.

Michael Totzeck, Carl Zeiss, Germany
Presentation: 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.

Peter Zoller, University of Innsbruck, Austria
Presentation: 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.

Quantum 2.0 technical presentations cover the range of emerging technologies quantum computing and simulation, quantum communications systems, quantum metrology and sensors, quantum interconnects and more.
