Slow light : invisibility, teleportation and other mysteries of light
\"Slow Light is a popular treatment of today's astonishing breakthroughs in the science of light. Even though we don't understand light's quantum mysteries, we can slow it to a stop and speed it up beyond its Einsteinian speed limit, 186,000 miles/sec; use it for quantum telecommunications; teleport it; manipulate it to create invisibility; and perhaps generate hydrogen fusion power with it. All this is lucidly presented for non-scientists who wonder about teleportation, Harry Potter invisibility cloaks, and other fantastic outcomes. Slow Light shows how the real science and the fantasy inspire each other, and projects light's incredible future.\" -- Back Cover.

The teleportation accident : a novel
In the declining Weimar Republic, Egon Loeser works as a stage designer. His hero devised the so-called Teleportation Device for whisking actors from one scene to another--a miracle, until the thing malfunctions, causing numerous deaths and perhaps summoning the devil himself.

Minimal port-based teleportation
There are two types of port-based teleportation (PBT) protocols: deterministic—when the state always arrives to the receiver but is imperfectly transmitted and probabilistic—when the state reaches the receiver intact with high probability. We introduce the minimal set of requirements that define a feasible PBT protocol and construct a simple PBT protocol that satisfies these requirements: it teleports an unknown state of a qubit with success probability p succ = 1 − N + 2 2 N + 1 and fidelity 1 − O ( 1 N ) with the resource state consisting of N maximally entangled states. This protocol is not reducible from either the deterministic or probabilistic PBT protocol. We define the corresponding efficient superdense coding protocols which transmit more classical bits with fewer maximally entangled states. Furthermore, we introduce rigorous methods for comparing and converting between different PBT protocols.

Star splitter
\"For Jessica Mathers, teleportation and planetary colonization in deep space aren't just hypotheticals--they're real. They're also the very real reason her scientist parents left her behind six years ago. Now she is about to be reunited with them, forced to leave behind everyone she knows and loves, to join their research assignment on Carver 1061c, a desolate, post-extinction planet almost 14 lightyears from Earth. Teleportation is safe and routine in the year 2198, but something seems to have gone very, very wrong. Jessica wakes up in an empty, and utterly destroyed, landing unit from the DS Theseus, the ship where she was supposed to rendezvous with her parents. But Jessica isn't on the Theseus orbiting Carver 1061c. The lander seems to have crashed on the planet's surface. Its corridors are empty and covered in bloody handprints; the machines are silent and dark. And outside, in the alien dirt, are the carefully, and recently, marked graves of strangers. Questions of self-determination and survival collide in this expertly crafted science fiction novel from Edgar Award-winning author Matthew J. Kirby. Kirby builds spine-tingling tension page-by-page in this imaginative and haunting story that spans both space and time\" -- Goodreads.

Quantum gate teleportation between separated qubits in a trapped-ion processor
Large-scale quantum computers will require quantum gate operations between widely separated qubits. A method for implementing such operations, known as quantum gate teleportation (QGT), requires only local operations, classical communication, and shared entanglement. We demonstrate QGT in a scalable architecture by deterministically teleporting a controlled-NOT (CNOT) gate between two qubits in spatially separated locations in an ion trap. The entanglement fidelity of our teleported CNOT is in the interval (0.845, 0.872) at the 95% confidence level. The implementation combines ion shuttling with individually addressed single-qubit rotations and detections, same- and mixed-species two-qubit gates, and real-time conditional operations, thereby demonstrating essential tools for scaling trapped-ion quantum computers combined in a single device.

Optimal port-based teleportation
Deterministic port-based teleportation (dPBT) protocol is a scheme where a quantum state is guaranteed to be transferred to another system without unitary correction. We characterise the best achievable performance of the dPBT when both the resource state and the measurement is optimised. Surprisingly, the best possible fidelity for an arbitrary number of ports and dimension of the teleported state is given by the largest eigenvalue of a particular matrix-Teleportation Matrix. It encodes the relationship between a certain set of Young diagrams and emerges as the optimal solution to the relevant semidefinite programme.

Stationary entangled radiation from micromechanical motion
Mechanical systems facilitate the development of a hybrid quantum technology comprising electrical, optical, atomic and acoustic degrees of freedom

, and entanglement is essential to realize quantum-enabled devices. Continuous-variable entangled fields—known as Einstein–Podolsky–Rosen (EPR) states—are spatially separated two-mode squeezed states that can be used for quantum teleportation and quantum communication

. An outstanding goal is to deterministically generate and distribute entangled states with a mechanical oscillator, which requires a carefully arranged balance between excitation, cooling and dissipation in an ultralow noise environment. Here we observe stationary emission of path-entangled microwave radiation from a parametrically driven 30-micrometre-long silicon nanostring oscillator, squeezing the joint field operators of two thermal modes by 3.40 decibels below the vacuum level. The motion of this micromechanical system correlates up to 50 photons per second per hertz, giving rise to a quantum discord that is robust with respect to microwave noise

. This noninvasive measurement scheme allows to infer information about otherwise inaccessible objects, with potential implications for sensing, open-system dynamics and fundamental tests of quantum gravity. In the future, similar on-chip devices could be used to entangle subsystems on very different energy scales, such as microwave and optical photons.
