The Quantum Quest for Dark Matter’s Elusive Axion Particle

If it exists, the axion goes beyond the basic design of elementary particles,” Paraoanu says. Paraoanu and the KVANTTI research study group will bring out their work using OtaNano devices. OtaNano is Finlands national research facilities for micro-, nano-, and quantum technologies. Particularly, Paraoanu will perform his work at the Low Temperature Laboratory, founded by Finnish physicist Olli V. Lounasmaa. Paraoanu is likewise included in InstituteQ and the new Finnish Quantum Flagship (FQF).

DarkQuantum Consortiums Quest for Axions
Researchers at Aalto University are setting out on a six-year task to find proof for the presence of axions. They will do so as part of a newly established consortium called DarkQuantum, together with scientists at the University of Zaragoza, who are coordinating the project, along with researchers at the French National Centre for Scientific Research, Karlsruhe Institute of Technology, and other partner organizations.
This brand-new consortium will be the very first to use the current quantum innovations to develop sensing units with unmatched scanning level of sensitivity. DarkQuantum was awarded EUR12.9 million on October 26 by the European Research Council, of which approximately EUR2 million is set aside for Aalto University Senior Lecturer and Docent Sorin Paraoanu and his Superconducting Qubits and Circuit QED (KVANTTI) research study group.

” We are peering into a deep, dark pit. If it exists, the axion goes beyond the standard model of primary particles,” Paraoanu states. “Such an observation would be equivalent in significance to the Higgs boson discovery in the early 2010s. At least with the Higgs boson, they knew where to start looking!”
” The nature of dark matter is among the biggest secrets in modern science,” includes University of Zaragoza Professor Igor Garcia Irastorza, who also heads the DarkQuantum consortium. “If dark matter is made of axions, we have a genuine possibility of detecting it with this project.”
Although there have actually been efforts to observe axions in the past, this newest undertaking will take advantage of quantum phenomena to enable researchers to much better filter out sound and duplicate their experiments with higher fidelity. Thats where Paraoanu and his team been available in.
Moving Mountains
Zoom into our little corner of the Milky Way galaxy, deep under the mountains covering the border in between Spain and France. This is the site of the Canfranc Underground Laboratory, which will house a high-frequency sensor the DarkQuantum scientists plan to construct. The other, low-frequency sensing unit will be found at the German Electron Synchrotron (DESY) in Hamburg.
Paraoanu and his KVANTTI group are mainly responsible for structure and tuning the high-frequency sensor, as well as composing the algorithms and software to use it. This sensing unit, called a haloscope, will probe the depths of the galactic halo looking for axions.
Putting the sensing unit deep underground assists get rid of cosmic background radiation, and it may provide an unique opportunity to at the same time study particular noise-reduction techniques for quantum computing.
” Our high-frequency sensing unit will be 10-100 times more sensitive than previous versions, and it will have the ability to scan on the scale of a couple of microelectron volts. It will utilize superconducting qubits– the same qubits used in quantum computer systems– however they will serve in a various role as detectors in this haloscope,” Paraoanu states.
Previous attempts to detect axions have actually used linear amplifiers, which tend to present noise and successfully take in particles into the system. Paraoanus sensor will depend on quantum nondemolition measurements, which will allow for duplicated try outs the very same particles.
” The theory recommends that, in an ultra-cold environment, we can introduce an electromagnetic field that will cause any axions present to decay into photons. If we discover any photons in the cavity, then we can conclude that axions are present in the system, and that they do indeed exist,” Paraoanu says.
Such an observation would be comparable in significance to the Higgs boson discovery in the early 2010s.”

Synergy Grant
The European Research Councils Synergy Grant is prestigious, and Paraoanu and his group are just the 2nd in Aalto Universitys history to receive the grant– the very first was awarded to Professor Risto Ilmoniemi for his continuous ConnectToBrain project.
The six-year job will be broken into 2 parts: a four-year scaling up phase, which includes the building, tuning and transportation of the haloscopes; and a two-year speculative stage, in which the team will collect information. Paraoanu expects to have openings for numerous scientist positions in the job in the coming years.
Other partner institutions named in the Synergy Grant consist of limit Planck Society for the Advancement of the Sciences, the Polytechnic University of Cartagena, and the Spanish National Research Council.
Paraoanu and the KVANTTI research group will bring out their work using OtaNano equipment. Paraoanu is also included in InstituteQ and the brand-new Finnish Quantum Flagship (FQF).

The DarkQuantum consortium, comprising global institutions, is leveraging quantum technologies in a mission to discover the mysteries of dark matter by discovering the elusive axion particle.
Aalto University scientists will penetrate the tricks of dark matter utilizing a quantum detector of unmatched level of sensitivity.
In the large darkness of the universe hides an undetectable sort of matter. Its existence is seen in the rippling ebb and flow of galaxies, however its never been straight observed. What tricks lie beneath the surface, brewing in the deep?
Physicists have long thought about the structure of dark matter, which is believed to be five times more plentiful than routine matter. Amongst completing hypotheses, one particle has become a promising candidate: the axion.
