Title: Quantum sensing with ultracold atoms

Abstract:

The best clocks in the world would go wrong by only one second over the age of the universe. This extraordinary precision is enabled by the frequency reference used in these clocks: ultranarrow optical transitions of atoms that are cooled to near standstill. These clocks enable searches for dark matter or changing fundamental constants, and will enable faster and GPS outage resilient telecommunication or cm-precision terrestrial navigation. Ultracold atoms are similarly used as test masses in precision accelerometers, which are already useful for underground exploration and further developed for dark matter and gravitational wave detection or inertial navigation.

Around the world efforts are underway to improve those quantum sensors or to render them cheaper, more compact and reliable. Our group contributes to these efforts by developing a novel type of clock, based on continuous superradiant lasing, and a continuous atom laser, which might enable better accelerometers.

Title: Compressed Σ-Protocol Theory

Abstract:

Σ-Protocols provide a well-understood and widely-used basis for two-party secure algorithmics. Combining ideas from secure MPC and from so-called Bulletproofs, we show how the communication of Σ-Protocols for proving general constraint-satisfiability problems can be compressed significantly. Based on Thomas Attema & Ronald Cramer(CRYPTO 2020) and subsequent joint works with Serge Fehr, Matthieu Rambaud and Lisa Kohl.

Workshop Dutch Secure Autonomous Cloud

  • 2020-12-10T13:00:00+01:00
  • 2020-12-10T16:00:00+01:00
December 10 Thursday

Start: 2020-12-10 13:00:00+01:00 End: 2020-12-10 16:00:00+01:00

Join the interactive workshop around the formation of the Dutch Secure Autonomous Cloud: a transparent, national cloud with security guarantees for the processing and storage of confidential information. The workshop serves as the first step in developing an ambitious national project proposal within the Long Term Programmes grant scheme.

The workshop serves as a platform for participants to present their questions and challenges to science and to exchange views. It is open to public authorities and representatives from all industrial and societal sectors. 

The workshop will take place on Thursday 10 December from 13.00 to 16.00, and is an initiative of Centrum Wiskunde & Informatica, Delft University of Technology, Eindhoven University of Technology, Radboud University, Vrije Universiteit, and the University of Amsterdam. Registration is required, through this webpage: https://portals.project.cwi.nl/dutch-secure-autonomous-cloud/registration

Background
Dutch governments and companies are completely dependent on foreign hardware and software suppliers for the storage, management and processing of growing amounts of data. As a result, they lose control over their data, and security standards are not guaranteed. Take, for example, the exchange of sensitive data; how sure are we that access rights to this data are securely verified? What guarantees are there that an attacker will not mimic or tamper with the verification process itself?

The answer is that at the moment there are virtually no guarantees and a complex hardware and software stack of American and Chinese origin: 'Big Tech' has to be trusted. The development of a transparent, national cloud, with security guarantees for the processing and storage of confidential information, could turn the tide and do justice to security standards, privacy legislation and digital autonomy.

Workshop
The workshop provides a platform for participants to present their questions and challenges to science and to exchange views. In addition, the more substantive and technical aspects of a national cloud facility will be discussed. The workshop serves as the first step in developing an ambitious national project proposal within the Long Term Programmes grant (minimum size: 30M€, first deadline: 26 January 2021).

Title: Governance of Quantum Technologies: From Theory to Adoption

Abstract:

Understanding the ethical, legal and societal implications of different quantum computing technologies will be crucial to facilitate its possible adoption. The benefits of quantum computing in areas such as health, communications, logistics and finance will only fully materialize if appropriate governance frameworks for the responsible use of the relevant technologies are developed. Governance questions will have to be examined at different levels. International law and norm development will be needed to address international aspects of access to quantum technologies. Economic regulation and intellectual property are needed to support functioning markets, innovation and market entry for start-ups. Fundamental rights protection (e.g. communications freedom, privacy and data protection) are important normative conditions for the development of relevant technologies. A regulation by design agenda for quantum technologies can support the early development of governance at the technological level, to support requirements such as verifiability, accountability and the reliability of the technologies.

Title: Quantum Algorithmic Measurements
Abstract: While the jury is still out on the prospects of the exciting developments on the quantum algorithmic supremacy front, a new and not less exciting development has been taking place over the past decade: the design of physical experiments has been completely reimagined to include computational elements such as error correction, multiparticle entanglement, and more. One can ask: how much would a full quantum computer help a quantum experimentalist in her lab? Would it improve the precision of certain measurements, or enable probing physical properties which were so far inaccessible? In a recent joint work with Cotler and Qi, we develop a theory of "quantum algorithmic measurements" (QUALMs) which is a hybrid of quantum black box algorithms (the black box is Nature itself) and quantum interactive protocols (with Nature); QUALMs aim to model the most general quantum experimental process, and enable studying such experiments from the point of view of their computational complexity. We use the QUALM model to show a new type of quantum exponential advantage: fully coherent experimental access to the measured system is provably exponentially more efficient than incoherent access, even if the latter is allowed to be adaptive (as usual, it is the lower bound which is difficult). For example, we show that the detection of symmetries in a quantum many-body system exhibits such an exponential separation in QUALM complexity. The theory of QUALMs raises many questions: what other quantum algorithmic ideas can be used to enhance our experimental abilities? And can coherent QUALMs be exponentially advantageous even in our noisy, pre-fault tolerance era? Throughout the talk, and in order to motivate QUALMs and my interest in the computational theory of measurements, I will give examples from the past decade based also on joint works with Arrad, Atia, Ben-Or, Eban, Mahadev, Retzker, Vazirani, and Vinkler.
