The DarkQuantum consortium, comprising international establishments, is leveraging quantum applied sciences in a quest to uncover the mysteries of darkish matter by detecting the elusive axion particle.
Aalto College researchers will probe the secrets and techniques of darkish matter utilizing a quantum detector of unprecedented sensitivity.
Within the huge darkness of the cosmos lurks an invisible type of matter. Its presence is seen within the rippling ebb and movement of galaxies, but it surely’s by no means been instantly noticed. What secrets and techniques lie beneath the floor, brewing within the deep?
Physicists have lengthy theorized concerning the composition of darkish matter, which is regarded as 5 instances extra considerable than common matter. Amongst competing hypotheses, one particle has emerged as a promising candidate: the axion.
DarkQuantum Consortium’s Quest for Axions
Scientists at Aalto College are setting out on a six-year challenge to seek out proof for the existence of axions. They may accomplish that as a part of a newly based consortium referred to as DarkQuantum, alongside researchers on the College of Zaragoza, who’re coordinating the challenge, in addition to researchers on the French Nationwide Centre for Scientific Analysis, Karlsruhe Institute of Know-how, and different accomplice establishments.
This new consortium would be the first to make use of the most recent quantum applied sciences to construct sensors with unprecedented scanning sensitivity. DarkQuantum was awarded €12.9 million on October 26 by the European Analysis Council, of which roughly €2 million is put aside for Aalto College Senior Lecturer and Docent Sorin Paraoanu and his Superconducting Qubits and Circuit QED (KVANTTI) analysis group.

“We’re peering right into a deep, darkish pit. If it exists, the axion goes past the usual mannequin of elementary particles,” Paraoanu says. “Such an remark can be comparable in significance to the Higgs boson discovery within the early 2010s. However not less than with the Higgs boson, they knew the place to begin trying!”
“The character of darkish matter is among the greatest mysteries in fashionable science,” provides College of Zaragoza Professor Igor Garcia Irastorza, who additionally heads the DarkQuantum consortium. “If darkish matter is product of axions, we now have an actual likelihood of detecting it with this challenge.”
Though there have been makes an attempt to look at axions previously, this newest endeavor will capitalize on quantum phenomena to allow researchers to higher filter out noise and repeat their experiments with higher constancy. That’s the place Paraoanu and his crew are available in.
Shifting Mountains
Zoom into our small nook of the Milky Approach galaxy, deep below the mountains spanning the border between Spain and France. That is the location of the Canfranc Underground Laboratory, which is able to home a high-frequency sensor the DarkQuantum researchers plan to construct. The opposite, low-frequency sensor can be positioned on the German Electron Synchrotron (DESY) in Hamburg.
Paraoanu and his KVANTTI group are primarily answerable for constructing and tuning the high-frequency sensor, in addition to writing the algorithms and software program to make use of it. This sensor, referred to as a haloscope, will probe the depths of the galactic halo looking for axions.
Placing the sensor deep underground helps remove cosmic background radiation, and it might supply a novel alternative to concurrently research sure noise-reduction strategies for quantum computing.
“Our high-frequency sensor can be 10-100 instances extra delicate than earlier iterations, and it will likely be in a position to scan on the size of some microelectron volts. It’ll use superconducting qubits—the identical qubits utilized in quantum computer systems—however they’ll serve in a distinct function as detectors on this haloscope,” Paraoanu says.
Earlier makes an attempt to detect axions have used linear amplifiers, which are inclined to introduce noise and successfully soak up particles into the system. Paraoanu’s sensor will depend on quantum nondemolition measurements, which is able to enable for repeated experiments with the identical particles.
“The idea means that, in an ultra-cold setting, we are able to introduce a magnetic area that may trigger any axions current to decay into photons. If we detect any photons within the cavity, then we are able to conclude that axions are current within the system, and that they do certainly exist,” Paraoanu says.
Such an remark can be comparable in significance to the Higgs boson discovery within the early 2010s.”

Synergy Grant
The European Analysis Council’s Synergy Grant is prestigious, and Paraoanu and his crew are solely the second in Aalto College’s historical past to obtain the grant—the primary was awarded to Professor Risto Ilmoniemi for his ongoing ConnectToBrain challenge.
The six-year challenge can be damaged into two components: a four-year scaling up part, which incorporates the development, tuning and transportation of the haloscopes; and a two-year experimental part, through which the crew will collect knowledge. Paraoanu expects to have openings for a number of researcher positions within the challenge within the coming years.
Different accomplice establishments named within the Synergy Grant embody the Max Planck Society for the Development of the Sciences, the Polytechnic College of Cartagena, and the Spanish Nationwide Analysis Council.
Paraoanu and the KVANTTI analysis group will perform their work utilizing OtaNano tools. OtaNano is Finland’s nationwide analysis infrastructure for micro-, nano-, and quantum applied sciences. Particularly, Paraoanu will carry out his work on the Low Temperature Laboratory, based by Finnish physicist Olli V. Lounasmaa. Paraoanu can be concerned in InstituteQ and the brand new Finnish Quantum Flagship (FQF).
