Our research group designs software for the computing technology of the future, especially quantum computing. Based on the laws of quantum mechanics, which tell us that systems and particles can be in multiple states at once, quantum computing is radically different from computing as we know it. Our quantum software requires fundamentally different techniques and approaches based on superposition, interference and entanglement. Ultimately, our research will result in better, faster and more reliable computer systems for society. Our research group is involved in QuSoft, the new Dutch research centre for quantum software.

Everyone of welcome to attend the QuSoft seminar with Gilles Brassard (Université de Montréal), with the title 'Probability and consequences of living inside a computer simulation'.


It is shown that under reasonable assumptions a Drake-style equation can be obtained for the probability that our universe is the result of a deliberate simulation. Evaluating loose bounds for certain terms in the equation shows that the probability is unlikely to be as high as previously reported in the literature, especially in a scenario where the simulations are recursive. Furthermore, we investigate the possibility of eavesdropping from the outside of such a simulation and introduce a general attack that can circumvent attempts at using quantum cryptography inside the simulation, even if the quantum properties of the simulation are genuine.
Joint work with Alexandre Bibeau-Delisle.
To appear (possibly on 3rd March 2021!) in the Proceedings of the Royal Society.

QuSoft Seminar: Cristina Cîrstoiu (Cambridge Quantum Computing)

Everyone is welcome to attend the online QuSoft seminar with Cristina Cîrstoiu (Cambridge Quantum Computing) with the title Variational fast forwarding for quantum simulation beyond the coherence time.

Trotterization-based, iterative approaches to quantum simulation (QS) are restricted to simulation times less than the coherence time of the quantum computer (QC), which limits their utility in the near term. Here, we present a hybrid quantum-classical algorithm, called variational fast forwarding (VFF), for decreasing the quantum circuit depth of QSs. VFF seeks an approximate diagonalization of a short-time simulation to enable longer-time simulations using a constant number of gates. Our error analysis provides two results: (1) the simulation error of VFF scales at worst linearly in the fast-forwarded simulation time, and (2) our cost function’s operational meaning as an upper bound on average-case simulation error provides a natural termination condition for VFF. We implement VFF for the Hubbard, Ising, and Heisenberg models on a simulator. In addition, we implement VFF on Rigetti’s QC to demonstrate simulation beyond the coherence time.  Finally, will present recent extensions that improve upon VFF.

Based on joint work with Zoe Holmes, Joseph Iosue, Lukasz Cincio, Patrick J. Coles & Andrew Sornborger from Los Alamos National Lab.

Workshop General Awareness Quantum Computing

  • 2021-02-26T13:00:00+01:00
  • 2021-02-26T16:30:00+01:00
February 26 Friday

Start: 2021-02-26 13:00:00+01:00 End: 2021-02-26 16:30:00+01:00

The workshop General Awareness Quantum Computing introduces you to the general principles of quantum computing and how such a computer can be used. The workshop aimed at an audience which does not have prior knowledge of quantum physics, but which does possess common knowledge of everyday computers. When completed, you will have a general understanding of the possibilities and what to expect of quantum computers in the future. This workshop gives you a clear focus on business relevance: no difficult physics, but a clear focus on disruptive opportunities and threats.

During the 3.5 hours the workshop takes, first some elementary concepts of quantum mechanics are explained. It becomes clear that a quantum computer has a tremendous potential to solve various problems, but there are formidable challenges in building the right soft- and hardware. Moreover, there exist many myths and suggestive promises about the possibilities of quantum computers, many of which turn out to be false. Together with other participants and the presenters, you will discuss how quantum computing influences your business and what you should do to create opportunities. One of Quantum.Amsterdam’s core values is to avoid hyping quantum technology, but rather to tell a balanced and honest story. We are grateful for collaboration with ING, Rabobank and ABN AMRO during the development of this workshop.

The workshop is given online using Cisco Webex or MS Teams. English language is used.

The next workshops will be provided on:
26 February 2021
26 March, 2021
23 April 2021
