Computer vision algorithms have become increasingly advanced over the past decades, enabling the development of sophisticated technologies to monitor specific environments, detect objects of interest in video footage and uncover suspicious activities in CCTV recordings. Some of these algorithms are specifically designed to detect and isolate moving objects or people of interest in a video, a task known as moving target segmentation.
While some conventional algorithms for moving target segmentation attained promising results, most of them perform poorly in real-time (i.e., when analyzing videos that are not pre-recorded but are being captured in the present moment). Some research teams have thus been trying to tackle this problem using alternative types of algorithms, such as so-called quantum algorithms.
Researchers at Nanjing University of Information Science and Technology and Southeast University in China recently developed a new quantum algorithm for the segmentation of moving targets in grayscale videos. This algorithm, published in Advanced Quantum Technologies, was found to outperform classical approaches in tasks that involve the analysis of video footage in real-time.
Scientists at the IBS Center for Quantum Nanoscience (QNS) at Ewha Womans University have accomplished a groundbreaking step forward in quantum information science. In partnership with teams from Japan, Spain, and the US, they created a novel electron-spin qubit platform, assembled atom.
An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.
“These simulations do not allow you to go back and alter your past, but they do allow you to create a better tomorrow by fixing yesterday’s problems today.”
Researchers at the University of Cambridge have demonstrated.
Quantum entanglement is a fundamental and intriguing phenomenon in quantum mechanics. It occurs when two or more particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other(s), even when they are separated by large… More.
For his work on techniques to generate quantum dots of uniform size and color, Bawendi is honored along with Louis Brus and Alexei Ekimov.
Moungi Bawendi, the Lester Wolfe Professor of Chemistry at MIT and a leader in the development of tiny particles known as quantum dots, has won the Nobel Prize in Chemistry for 2023. He will share the prize with Louis Brus of Columbia University and Alexei Ekimov of Nanocrystals Technology, Inc.
The researchers were honored for their work in discovering and synthesizing quantum dots — tiny particles of matter that emit exceptionally pure light. In its announcement this morning, the Nobel Foundation cited Bawendi for work that “revolutionized the chemical production of quantum dots, resulting in almost perfect particles.”
Hindsight, as they say, is 20/20, but sometimes it would be nice to have known the outcomes before making a choice. This is as true in day-to-day life as it is in quantum mechanics. But it seems that the quantum world has something we do not have: a way to alter yesterday’s choices today, before they become tomorrow’s mistakes.
None of this is real time-travel. Physicists remain skeptical about that possibility. However, it is possible to simulate a closed time-loop with quantum mechanics, thanks to the property of entanglement. When two particles are entangled, they are in a single state even if they are separated by huge distances. A change to one is a change to the other, and this happens instantaneously.
So a particle can be prepared for an experiment, entangled, and sent to the experiment. Then scientists can modify its entangled companion, changing the way the particle in the experiment behaves.

For most of us, the passage of time flies in just one inexorable direction.
But for theoretical quantum physicists, time’s direction isn’t quite so inflexible. It’s possible to theoretically model, simulate, and observe the backwards flow of time in ways that are impossible to achieve in the real world.
And now, scientists have shown that simulations of backwards time travel can help solve physics problems that cannot be resolved with normal physics.
A new method identifies the most sensitive measurement that can be performed using a given quantum state, knowledge key for designing improved quantum sensors.
A quantum sensor is a device that can leverage quantum behaviors, such as quantum entanglement, coherence, and superposition, to enhance the measurement capabilities of a classical detector [1–5]. For example, the LIGO gravitational-wave detector employs entangled states of light to improve the distance-measurement capabilities of its interferometer arms, allowing the detection of distance changes 10,000 times smaller than the width of a proton. Typically, quantum sensors use systems prepared in special quantum states known as probe states. Finding the ideal probe state for a given measurement is a focus of many research endeavors. Now Jarrod Reilly of the University of Colorado Boulder and his colleagues have developed a new framework for optimizing this search [6].
