Quantum Technology Labs

The goal of the NLPQT project is development of country-wide infrastructure to enable practical utilization of properties of individual quantum objects, with particular emphasis on the possibility of using single photons in quantum communication. NLPQT infrastructure will enable research and development work, leading to the design, launching and development of complex and secure systems using quantum key distribution (QKD) techniques and quantum communication, as well as integration of these solutions with other mechanisms used at present to secure data transmitted over IT and telecommunication systems. Further, test workstations enabling the development of applications of properties of single quantum objects, such as electrons, quantum dots, or atoms will be established within the framework of the NLQPT project.

We will establish local QKD and quantum communication networks in Poznań and Warsaw, on the basis of urban network infrastructures.  Moreover, a long-distance QKD connection will be established between Poznań and Warsaw by the uses of the academic PIONIER optical fiber network infrastructure.  The links will support installation and integration of one production system and one R&D system. The Quantum Technology Labs quantum communications infrastructure will be completed by test workstations for innovative quantum communication solutions and photonic quantum network interfaces. Additional workstations will address quantum-enhanced imaging, atomic interferometry, photon-matter interactions, and solid-state based quantum technologies.

We anticipate the Quantum Technology Labs infrastructure to enable the following R&D activities:

  • research leading to designing, launching and developing complex and secure systems using QKD and quantum communication techniques and integration of these solutions with other mechanisms used to secure data in other layers of IT systems/ transmission channels,
  • providing industrial partners with new solutions in terms of encoding and security of data transmitted, as well as integration of various security mechanisms,
  • integration of the NLPQT network in the cryptographic key quantum distribution network on the European scale,
  • advanced quantum communication research, such as:
  • research in the field of long-distance quantum communication using the fiber optics technology and a satellite receiver,
  • research in the field of optical transmission encoding and authentication (including time and frequency),
  • development of quantum cryptography methods based on transmission of single photons, characterized by exceptionally high information capacity,
  • implementation of high performance QKD protocols with guaranteed safety levels, requiring no authentication of the transmitter and receiver stations,
  • high-performance quantum authentication in distributed architectures.

Another application of single photons is long-distance transmission of quantum information. Optical links based on single photon transmission make it possible to generate quantum superpositions between remote physical systems, making the quantum Internet concept come true. In this field, the planned infrastructure will allow for:

  • development of methods for long-distance transmission of quantum superpositions and quantum entanglement to generate quantum superpositions of various types of objects,
  • development of quantum computation and quantum simulations,
  • application of large-scale superpositions in metrology, in particular, time and frequency metrology.

Quantum properties of light also play a significant role in issues associated with detection of light signals of very low intensity, e.g. in medical imaging. As a part of the project, we will offer the interested companies and researchers support and cooperation in research in the following fields:

  • development of new quantum imaging techniques and application of the existing ones,
  • development of new high temporal and spatial resolution detectors (e.g. for fluorescent microscopy),
  • characterization of detectors and cameras in the weak light regime.

The equipment developed as a part of the NLPQT will also be used to conduct innovative research in such fields as:

  • quantum photonics (analysis of atom nanostructures and systems under the conditions of coherent excitation at cryogenic temperatures, quantum yield measurements of single photon detectors using a method based on time-resolved photon pair detection, dispersion measurements in materials undergoing the second harmonic generation process and parametric frequency splitting). Responsible researcher: Piotr Kolenderski (NCU), http://spa.fizyka.umk.pl/
  • physics of ultracold atoms and particles (including spectroscopy of ultracold particles consisting of at least three atoms, research on Kondo effect and its presence in boson-fermion mixtures, quantum simulations of dipole systems with long-distance effects, quantum calculations using internal particle levels as qubits). Responsible researcher: Mariusz Semczuk (UW), http://ultracold.fuw.edu.pl/
  • layered materials (production of high-performance solotronic emitters that allow for recording and storage of information in ion quantum state, development of methods for quick optical characterization of semiconductor layers and multi-layers for optoelectronics, designing of semiconducting nano- and microsensors of a new type, based on the technology for production of transducers and microgenerators of acoustic waves propagating on the semiconductor surface).
