Faster-Than-Ever Quantum Entanglement Generation!

By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation

Quantum entanglement is one of the most thought-provoking and counterintuitive ideas of modern physics. Two particles that are spatially well-separated in the spacetime network display a correlation among their properties and an act of measurement on one of the pairs can affect the other particle instantaneously despite the lack of a communication channel, which is remarkable and bizarre at the same time. Albert Einstein being a skeptic of the idea, referred to entanglement as “Spooky Action at a Distance” even though it was his work that led up to its realization [1].

Although there is a sense of mystery associated with the phenomenon, it has led to the development of numerous technologies that govern our modern world. For instance, it has led to the creation of quantum bits, or qubits, that are essential for quantum computing. Furthermore, there has been a lot of advancement in large-scale quantum...

Manipulating Quantum Laws to Create Efficient Quantum Devices and Enhancing Quantum Communication Technology

 By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation 

This year’s Nobel prize in physics has been awarded to three physicists for fundamental discoveries in the foundations of quantum mechanics. Specifically, it has been awarded for proving the violation of Bell’s inequalities through experiments involving the entanglement of photons, and the advancement of the science of quantum information, in general, brought about by the discoveries. RSF Physicist Dr. Ines Urdaneta has already described this year’s Nobel prize in her latest article. The reader is advised to check it out for more details.  

In this article, our focus is on the manipulation of this fundamental knowledge posed by some of the related work in the creation of efficient quantum devices. Our aim is to discuss some of the recent progress in quantum technology which apparently builds on the laws of quantum mechanics and...

Dynamical Topological Phase, Driven by a Fibonacci Pulse, Protects Entanglement

By Dr. Inés Urdaneta, Physicist at Resonance Science Foundation

In former works we have addressed the importance of topology in material science and quantum systems.  

The word topology refers to the contours of a surface or the shape of an object. In mathematics, topology classifies objects by the number of holes they have. A ball is a sphere with no hole, whereas a doughnut, with its one hole, is topologically different. The ball is topologically equivalent to an apple, and a doughnut to a cup, but not to a ball or a pretzel, since going from one topology to another would require a dramatic change, like ripping a hole. This topological feature or state provides a sort of stability to the system, and for this reason, the topological states discovered in some materials are robust and resist disruptions, unless they are as dramatic as the one mentioned previously.

Topological materials provide certain electronic states that persist despite a modification to their physical...

Researchers Discover a Theoretical Correspondence Between Topology and Quantum Entanglement

By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation

Topology is a branch of mathematics concerning the properties of geometric objects and their shapes. These properties are essentially invariant under continuous deformations such as stretching, twisting, etc. Entanglement on the other hand is purely a physical phenomenon wherein two particles can influence each other instantaneously irrespective of the spatial distance between them.

In new research published in the journal Physical Review X, Charles Kane, who is the Christopher H. Browne Distinguished Professor of Physics in U. Penn's School of Arts & Sciences established a conceptual duality between topology and entanglement along with his collaborators [1].

Consider a sphere and a donut. The difference between the two lies in the fact that a donut, which has a toroidal topology, is specified by a single hole whereas there are no holes in a sphere. In this sense, a coffee mug...

Atomic Clocks and Quantum Time Reversal

By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation

The quantum world essentially contains a myriad of intriguing phenomena and continues to add up to the imagination of science explorers. One such phenomenon concerns the oscillations at the level of atoms which forms the basis for the creation of quantum devices like atomic clocks and sensors. The elements that are used in modern day atomic clocks involve ytterbium, caesium among others. A significant part of the advances in contemporary atomic clocks research is mainly because of its usability in certain scenarios like dark matter and gravitational wave detections. 

Due to the subtle nature of these physical events, sometimes unwanted noise from the surrounding environment can cause distortions in the signal and negatively impact the results. In order to overcome this major challenge, physicists from the Massachusetts Institute of Technology (MIT) have come up with a viable proposition and that is to use a...

Entanglement over 33 Km! New Distance Record

By Inés Urdaneta, Physicist at Resonance Science Foundation

Entanglement, coined by Einstein as “spooky action at a distance”, has achieved a new record for long distance communication, as a team from Ludwig-Maximilians-University Munich (LMU) and Saarland University have reported in Nature [1].

Entanglement is the property by which two quantum objects, such as atoms, are connected in such a way that their quantum state can’t be described independently from the other. Hence, when a change happens in one of the objects, the other object modifies its state as to preserve the relationship between them, no matter the distance between them.  

This feature seems to defy Einstein’s special relativity, in which nothing, not even information could travel faster that the speed of light. It is as if the correlation between entangled particles was preserved “instantaneously” by some miraculous mechanism implying an intrinsic nonlocality of...

Research Team Demonstrates Nonlinear Two-Level Coupling of Quantum Time Crystals

By: William Brown, Biophysicist at the Resonance Science Foundation

We first reported on the break-through observation of a time crystal in our article Time Crystals – A New Phase of Matter. Now, in the next major development, the same team who generated the new phase of matter have created the first time-crystal two-body system in an experiment that seems to bend the laws of physics.

As the name would imply, a time crystal is not an easy system to prepare and experiment with. Perpetual ground state motion in equilibrium defines a time crystal, however observing such motion is famously unfeasible, because experimentally a time crystal only achieves stability if it is isolated from the environment and the observer— shielding the pure quantum state of the system from decoherence— where either the perpetuity or equilibrium requirements can be “bent”. Much like the quantum mechanical bit, or qubit, coupling separate quantum time crystals while...
