International Year of Quantum Science and Technology

Share

2025 is the International Year of Quantum Science and Technology. 

From its inception 100 years ago, the field of quantum mechanics has produced some of the most unexpected insights into the natural world, unlocking a vast universe of technologies that enhance our daily lives in ways we may not even realize. From GPS and smartphones, to cybersecurity and precision instruments for defense, to exquisitely accurate measurements that underpin our commercial transactions, quantum has made our technologies more accurate, more trustworthy, and more secure. 

Join NIST in celebrating the many outstanding achievements of our researchers and collaborators in advancing the frontiers of quantum and help us usher in the next 100 years of possibility. And learn a little bit more about quantum along the way!

100 Years of Quantum Research

Throughout the year, we plan to highlight some of NIST's most influential and important papers that helped advance the frontiers of quantum science research. 

Our first batch of papers highlights NIST's research in basic quantum science, which has laid a foundation on which we continue to build as more discoveries are made, in turn leading to more technologies and lasting impacts on our quality of life. Papers highlighted include ones from as far back as 1957!

See what papers we're highlighting

Make sure to check back throughout the year as we add additional papers from NIST authors.

quantum terms explained

What is Entanglement?
What is Entanglement?
Experience quantum entanglement with a playful twist — featuring our "quantum deer" that might just exclaim, "Oh, deer!" or "Deer me!" Discover how entangled particles mimic each other, no matter the distance, and see how this quirky phenomenon is paving the way for breakthroughs in computing, sensing and communication. Oh, deer!
What are Qubits?
What are Qubits?
Step into the fascinating world of quantum mechanics in this quick explainer and find out a little BIT about what makes QUBITS so special. What bits are for classical computers, qubits are for the quantum computers and atomic clocks of the future.
What is Quantization?
What is Quantization?
Step into the fascinating world of quantum mechanics in this quick explainer! We break down how quantization works and how particles like electrons can only exist in specific, discrete states—much like an employee who can only stand on designated steps of a staircase.
What is Decoherence?
What is Decoherence?
Decoherence is a big challenge in quantum computing. But what is it? This quick explainer explains how fragile quantum states, like qubits, can lose their quantum magic when they interact with the environment. Mastering decoherence could unlock the future of quantum technology.
What is Superposition?
What is Superposition?
Superposition is a key principle of quantum physics. But what does it mean? Our NIST scientist explains how particles, like qubits, can exist in multiple states at once—both 0 and 1—until measured. Explore this mind-bending concept and see how superposition powers the future of quantum technology.
