2025 Nobel Physics Prize

By Adedapo Adesanya

The Nobel Prize in Physics 2025 was on Tuesday awarded to the American trio of John Clarke, Michel H. Devoret, and John M. Martinis for their experiments on a chip which revealed quantum physics in action.

The Royal Swedish Academy of Sciences, which awards the prize, according to a statement, said the recognition was “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit”

The Physics laureates conducted experiments with an electrical circuit in which they demonstrated both quantum mechanical tunnelling and quantised energy levels in a system big enough to be held in the hand.

This helps answer a major question in physics, which asks the maximum size of a system that can demonstrate quantum mechanical effects.

Quantum mechanics allows a particle to move straight through a barrier, using a process called tunnelling. As soon as large numbers of particles are involved, quantum mechanical effects usually become insignificant.

According to the committee, the laureates’ experiments demonstrated that quantum mechanical properties can be made concrete on a macroscopic scale.

In 1984 and 1985, John Clarke, Michel H. Devoret and John M. Martinis conducted a series of experiments with an electronic circuit built of superconductors, components that can conduct a current with no electrical resistance.

In the circuit, the superconducting components were separated by a thin layer of non-conductive material, a setup known as a Josephson junction. By refining and measuring all the various properties of their circuit, they were able to control and explore the phenomena that arose when they passed a current through it.

Together, the charged particles moving through the superconductor comprised a system that behaved as if they were a single particle that filled the entire circuit.

This macroscopic particle-like system is initially in a state in which current flows without any voltage. The system is trapped in this state, as if behind a barrier that it cannot cross.

In the experiment, the system shows its quantum character by managing to escape the zero-voltage state through tunnelling. The system’s changed state is detected through the appearance of a voltage.

The committee added that the laureates could also demonstrate that the system behaves in the manner predicted by quantum mechanics – it is quantised, meaning that it only absorbs or emits specific amounts of energy.

“It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises. It is also enormously useful, as quantum mechanics is the foundation of all digital technology,” says Olle Eriksson, Chair of the Nobel Committee for Physics.

The Nobel committee added that this year’s candidates provided opportunities for developing the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors.

On Monday, the Nobel committee had awarded the prize in medicine to three scientists, two Americans and one Japanese.

On Wednesday, the prize will awarded in Chemistry followed by literature on Thursday, peace of Friday, and economics next week Monday.

President Bola Tinubu has approved the renaming of the Petroleum Technology Development Fund (PTDF) College of Petroleum and Energy Studies, Kaduna, in honour of the late statesman, General Shehu Musa Yar’Adua, in a move aimed at preserving his legacy while strengthening Nigeria’s specialised energy education framework.

The PTDF announced that, following a presidential directive, the institution will now be known as the General Shehu Musa Yar’Adua University of Geological Sciences and Engineering Technology.

In a statement, the Fund said the renaming reflects the federal government’s recognition of Yar’Adua’s contributions to national unity and Nigeria’s democratic evolution.

The late statesman, who died in 1997, was a prominent Nigerian soldier, politician, and businessman. He served as the Chief of Staff, Supreme Headquarters, under General Olusegun Obasanjo’s military administration from 1977 to 1979. He was the elder brother of former Nigerian President Umaru Musa Yar’Adua.

“This historic renaming honours the enduring legacy of the late statesman, General Shehu Musa Yar’Adua, celebrating his profound contributions to national unity and the democratic journey of Nigeria,” the PTDF stated.

The institution, established to develop high-level manpower and technical expertise for Nigeria’s petroleum and energy industries, is expected to continue its academic and research activities without disruption despite the name change.

According to the PTDF, the university will maintain its focus on delivering advanced education, research and technology-driven solutions for the country’s oil, gas and emerging renewable energy sectors.

“The institution remains firmly committed to its mandate of delivering world-class research, specialised training, and cutting-edge engineering technology solutions to power Nigeria’s oil, gas, and renewable energy sectors,” the statement added.

The Fund further assured students, academic partners, industry stakeholders and development institutions that all existing programmes, collaborations and operational activities would continue seamlessly under the university’s new identity.

“All ongoing academic programs, partnerships, and operations continue uninterrupted under this new institutional identity,” PTDF said.

The renaming comes as Nigeria intensifies efforts to build local capacity and technical expertise to support energy transition goals, deepen indigenous participation in the petroleum industry and strengthen research-driven innovation across the energy value chain.

A sustainability-focused programme known as Airtel Green Schools has been launched by Airtel Africa Foundation, as part of activities to commemorate the 2026 World Environment Day, themed Climate Action.

The initiative will create environmental learning spaces in primary and secondary schools, with the spaces to be branded Airtel Garden.

Already, the company’s 10 adopted schools, located in nine states across the country’s six geopolitical zones, have been onboarded as Green Schools.

Each of the schools now features an Airtel Garden, with dedicated sections for edible crops, fruit trees and shade trees, enabling pupils to learn firsthand about food cultivation, biodiversity and the importance of increasing green cover to help mitigate the effects of climate change.

The gardens also incorporate composting stations where organic waste generated within the school environment can be converted into nutrient-rich compost. To boost circular economy practices, plastic recycling segments have also been built into repurpose common wastes such as plastic bottles and tyres.

The beneficiary schools of the programme include St. George’s Nursery and Primary School, Ipaja, Lagos; Yahaya Primary School, Zaria; Iyeru-Okin Primary School, Iyeru-Okin, Kwara; St. John Primary School, Ijebu Igbo, Ogun State, and Community Primary School, Amumara, Imo State.

Others are Presbyterian Primary School, Ediba, Cross-River; Migrant Farmers Community Primary School, Umuahia, Abia State; Gwange III Primary School, Maiduguri, Borno State; Mayflower Secondary School, Ikenne, Ogun State; and Government Day Primary School, Gombe State.

“We are excited to inaugurate Airtel Green Schools, which are designed to go beyond awareness and create real behavioural change within Nigeria’s school communities.

“Through the Restore, Reduce and Educate pillars, we are equipping young people with practical tools such as gardens, recycling awareness, and environmental learning resources.

“Our goal is to create a replicable Green School model that can be scaled and sustained over time, ensuring that environmental education becomes part of everyday learning for the children in our adopted schools,” the chairman of the foundation, Mr Segun Ogunsanya, stated.

Also speaking, the chief executive of Airtel Nigeria, Mr Dinesh Balsingh, said, “Climate action becomes meaningful when awareness is translated into action. Through the Airtel Garden, we are creating living classrooms where pupils can learn practical lessons about environmental stewardship, sustainable agriculture, waste management and the importance of protecting our planet.

“We believe that empowering young people with these experiences today will help shape a more environmentally responsible generation tomorrow.”
