The 2025 ICTP Prize has been awarded to Titas Chanda of IIT-Madras and Sthitadhi Roy of the International Centre for Theoretical Sciences, Bengaluru, the International Centre for Theoretical Physics (ICTP) has said.
A statement said the grant “recognises the winners’ exceptional and archetypal contributions to the mentation of quantum many-body systems, astatine the interface of condensed substance and quantum accusation science,” and that their enactment has “opened caller directions successful the knowing of non-equilibrium dynamics of quantum systems, quantum correlations, and measurement-driven signifier transitions.”
That is, the physicists survey galore interacting quantum particles utilizing ideas from some condensed substance physics and quantum accusation science.
This enactment is applicable to problems successful keeping quantum devices — similar quantum computers and sensors — nether power and knowing what they bash erstwhile they’re not successful equilibrium.
Quantum many-body systems are those with tons of quantum ‘pieces’, e.g. electrons successful a coagulated oregon atoms successful an ultracold gas, whose corporate behaviour is dominated by however they interactions. Because the particles power each other, physicists can’t usually recognize the full strategy by solving for 1 particle astatine a time.
Condensed substance is the subdivision of physics dealing with corporate behaviour successful materials and engineered matter, including magnets and superconductors. It tries to reply questions like: what phases exist? Why bash they magnetise? How bash they behaviour heat? What happens adjacent a signifier transition? And truthful on. Likewise quantum accusation science treats quantum states arsenic accusation and uses quantities similar entanglement and entropy to characterise and manipulate them.
According to the ICTP, Dr. Chanda, an adjunct prof astatine IIT-Madras, shared the prize for contributions to quantum accusation subject and quantum many-body physics, including enactment connected quantum correlations and unfastened quantum systems arsenic good arsenic applications specified arsenic “quantum batteries, connection protocols, and assets theories.”
His enactment includes the improvement of numerical tools and results crossed areas that the merchandise listed arsenic quantum optics, acold atoms, and powerfully correlated systems, the connection added.
Dr. Roy, an adjunct prof astatine the International Centre for Theoretical Sciences successful Bengaluru, nether the Tata Institute of Fundamental Research, shared the prize for contributions to “the non-equilibrium dynamics of quantum many-body systems,” including enactment connected “measurement-induced phenomena, many-body localisation, and emergent phases of quantum matter.”
In its release, the ICTP said his probe includes results connected “hybrid quantum circuits” and “protocols that harness measurements to hole exotic topological and dynamical phases.”
The ICTP Prize is an yearly matter and has been awarded since 1982 to young scientists from processing countries. It carries a certificate and a currency component. Past winners from India see Mohit Kumar Jolly, Narendra Ojha, Aninda Sinha, Shiraz Minwalla, Ashoke Sen, and G. Baskaran.
Each year’s prize is besides fixed successful honour of a idiosyncratic who made “outstanding” contributions to the tract that that year’s prize focuses on. The 2025 prize was dedicated to the representation of Italian physicist Giancarlo Ghirardi, “whose tireless enactment connected the foundations of quantum mechanics” the merchandise said anticipated “entanglement-based modern quantum accusation methods”.
The ICTP was founded by Pakistani physicist and Nobel laureate Abdus Salam successful 1964 to enactment scientists from processing countries.
