Quantum Technology Summer in Budapest

2024. June 13.

Three subsequent quantum technology events take place between June 10th and 20th in Budapest, all co-organised by scientists of the BME Institute of Physics.
 
The Defects in Solids for Quantum Technologies (DSQT) conference takes place from June 10 to 14 at the Roland Eötvös University (ELTE). Research in the past few decades revealed that point defects in semiconductors can be used in all four main areas of quantum technology -- quantum computing, quantum simulation, quantum communication, as well as quantum sensing. The conference brings world-leading experts of the field to Budapest. Hungarian members of the international organizing committee hosting the event are Ádám Gali (HUN-REN Wigner Research Centre for Physics and BME Institute of Physics) and Viktor Ivády (ELTE).
 
On June 17-18, the meeting of the OpenSuperQPlus consortium, consisting of 28 European organizations, will take place in the BME Q building. The long-term goal of this Horizon Europe project, carried out in a strong  academic-industrial cooperation, is to develop a quantum computer based on superconducting technology, consisting of 1,000 quantum bits. Among the Hungarian research centers, BME's Institute of Physics and the  HUN-REN Wigner RCP participate in the OpenSuperQPlus project, providing theoretical support for the development of the quantum computer. The Budapest meeting is organized by János Asbóth and András Pályi on behalf of BME, and Orsolya Kálmán and Zoltán Zimborás on behalf of HUN-REN Wigner RCP.
 
On June 19-20, a conference on Recent Advances in Quantum Computing and Technology (ReAQCT) will take place at the Bosch Budapest Innovation Campus. The event is jointly organized by several universities and research centers in Budapest. BME is represented in the organizing committee by András Pályi (BME TTK), and in the program committee by János Asbóth (BME TTK) and Eszter Udvary (BME VIK).
 
The DSQT and ReAQCT conferences are supported by the Quantum Information National Laboratory of Hungary.

Bichromatic control of semiconductor qubits

2024. February 10.

Research from a collaboration between TU Delft, ELTE and BME explores a new way to control semiconductor-based quantum bits. Published as Editors’ Suggestion in Physical Review Letters.
 
Most of today’s conventional computing technology is based on semiconductors. In contrast, the highest-valued quantum computing platforms are currently based on superconductors, or arrays of atoms levitated in vacuum. Quantum computer prototypes based on semiconductors do exist, but they lag behind their more advanced competitors.
 
Quantum logical gates are performed, in all of these platforms, by sending short pulses of electromagnetic radiation on the qubits. In neutral atom quantum computers, certain gates are done by `bichromatic transitions' (sometimes called `two-photon transitions'), which result from the interplay of radiation of two different frequencies. In the new paper, the researchers report the discovery and the detailed analysis of bichromatic coherent control of semiconductor-based single-electron qubits. Hungarian researchers, including associate professor András Pályi of the BME Institute of Physics, contributed to the results by the in-depth theoretical analysis explaining the experiments performed in the group of Menno Veldhorst at TU Delft. The authors expect that the new mechanism will be utilized for selective qubit addressing, and efficient parallelisation of logical operators, in large-scale two-dimensional qubit arrays.
 

This research was funded at BME by the NKFIH via the Quantum Information National Laboratory of Hungary and the grant FK132146, as well as the Horizon Europe grant IGNITE.
