A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

The experimental layout of the sender Alice and the receiver Bob. Alice’s setup contains the excitation and collection setup of the single photon source, and a Sagnac-like polarization modulator for ...

Conventional encryption methods rely on complex mathematical algorithms and the limits of current computing power. However, with the rise of quantum computers, these methods are becoming increasingly ...

Theoretical advancements in quantum metrology by Dr. Mackoit-Sinkeviciene are shaping the future of quantum technologies and ...

Quantum computers could rapidly solve complex problems that would take the most powerful classical supercomputers decades to ...

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment ...

When two observers measure an entangled state, the frequencies of their observed results manifest the strength of quantum theory. Extreme values governing these statistics have now been successfully ...
