Research Breakthrough in Entanglement Could Lead to High-Dimensional Encoding of Quantum Information, Future Quantum Devices
Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.

Exchanging Information With Photons Across Long Distances Just Got Easier (Sorta)
Building a quantum network one node at a timeThis illustration of a nanoscale node created by the lab of Nick Vamivakas, professor of quantum optics and quantum physics, shows a closeup of one of an array pillars, each a mere 120 nanometers high. Each pillar serves as a location marker for a quantum state that […]
Teleportation is possible if…
Teleportation is possible if… Is teleportation possible? Yes, in the quantum world Full release… “Beam me up” is one of the most famous catchphrases from the “Star Trek” series. It’s the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise. While human teleportation currently exists only in […]
Teleportation Between Electrons? University Research Suggests So
Teleportation Between Electrons? University Research Suggests So Is teleportation possible? Yes, in the quantum world Key points… + Quantum teleportation is a demonstration of what Albert Einstein famously called “spooky action at a distance”—also known as quantum entanglement. In entanglement—one of the basic of concepts of quantum physics—the properties of one particle affect the properties […]
Being Clever About Correcting Qubit Errors
Being Clever About Correcting Qubit Errors Scientists one step closer to a fully functioning quantum computer Selected notes ~ + Just like ordinary computers, however, quantum computers need a way to transfer information between qubits, and this presents a major experimental challenge. + “A quantum computer needs to have many qubits, and they’re really difficult […]
Doughnut-Shaped Pulses of Light to Transfer Data?
University of Rochester researchers have published a list of ’12 Herculean tasks’ they believe will inspire the next quantum scientists. One of the authors demonstrated the use of ‘twisted light’ to slightly more than double data-throughput per photon. The approach utilized the mechanics of orbital angular momentum (OAM) of photons for encoding the data. Two of the tasks put forth to ponder are, “What is the future of quantum coherence, squeezing, and entanglement for enhanced super resolution and sensing?”, “How can we solve some of humanity’s biggest problems through new quantum technologies?”
