AWS Officially Launched Its Quantum Computing Service
Posted by Genevieve Klien in categories: computing, quantum physics
It seemed as if AWS was lagging behind Google, Microsoft, and IBM when it comes to quantum computing but they’ve finally taken a step forward with their latest announcement.
AWS has officially announced the preview launch of its first-ever quantum computing service known as Braket. However, AWS is still not building their own quantum computer. Instead, they chose to partner with IonQ, Rigetti, and D-Wave in providing computing services through the cloud.

Detecting the Origin of Cancer‐Mobile Quantum Probe for Single Cancer Stem Cell Detection
Posted by Paul Battista in categories: chemistry, quantum physics
Cancer stem cells (CSC) are believed to be the driving force of cancer metastases and are a rare population of self‐renewing cells that contribute majorly to the poor outcomes of cancer therapy. The detection of CSC is of utmost importance to shed light on the indestructible nature of certain solid tumors and their metastatic ability. However, tumors tend to harbor CSCs in a specialized niche, making the detection process difficult. Currently, there is no method available to detect CSCs. The significance of this work is twofold. First, to the best of the knowledge, it is the first time that the detection of CSC is demonstrated. This approach simultaneously detects both the phenotypic and the metabolic state of the cell, thus enabling universal detection of CSC with high accuracy. Second, to the best of the knowledge, for the first time, light is shed on cell chemistry of CSC in their dedicated niche to facilitate a better understanding of the key players involved in the metabolic rewiring of CSC. This work will enable a better understanding of the fundamentals of CSCs, which are critical for the early diagnosis of cancer and the development of therapies for the cure of cancer.

Researchers Teleport Information Between Two Computer Chips for the First Time
Posted by Saúl Morales Rodriguéz in categories: computing, internet, nanotechnology, particle physics, quantum physics
For the first time, researchers and scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU), have achieved quantum teleportation between two computer chips. The team successfully developed chip-scale devices that are able to harness the applications of quantum physics by generating and manipulating single particles of light within programmable nano-scale circuits.
Unlike regular or science fiction teleportation which transfer particles from one place to another, with quantum teleportation, nothing physical is being transported. Rather, the information necessary to prepare a target system in the same quantum state as the source system is transmitted from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location.
In a feat that opens the door for quantum computers and quantum internet, the team managed to send information from one chip to another instantly without them being physically or electronically connected. Their work, published in the journal Nature Physics, contains a range of other quantum demonstrations. This chip-to-chip quantum teleportation was made possible by a phenomenon called quantum entanglement. The entanglement happens between two photons (two light particles) with the interaction taking place for a brief moment and the two photons sharing physical states. Quantum entanglement phenomenon is so strange that physicist Albert Einstein famously described it as ‘spooky action at a distance’.

Information teleported between two computer chips for the first time
Posted by Tracy R. Atkins in categories: computing, internet, particle physics, quantum physics
Scientists at the University of Bristol and the Technical University of Denmark have achieved quantum teleportation between two computer chips for the first time. The team managed to send information from one chip to another instantly without them being physically or electronically connected, in a feat that opens the door for quantum computers and quantum internet.
This kind of teleportation is made possible by a phenomenon called quantum entanglement, where two particles become so entwined with each other that they can “communicate” over long distances. Changing the properties of one particle will cause the other to instantly change too, no matter how much space separates the two of them. In essence, information is being teleported between them.
Hypothetically, there’s no limit to the distance over which quantum teleportation can operate – and that raises some strange implications that puzzled even Einstein himself. Our current understanding of physics says that nothing can travel faster than the speed of light, and yet, with quantum teleportation, information appears to break that speed limit. Einstein dubbed it “spooky action at a distance.”

The Biggest Myth In Quantum Physics

There are a slew of ways to interpret just what’s happening when you make an observation. The biggest myth of all is that you need one.

NSA, Army Seek Quantum Computers Less Prone to Error
Posted by Dan Kummer in categories: computing, information science, military, privacy, quantum physics
Even ordinary computers flip a bit here and there, but their quantum cousins have a lot more ways to go wrong.
As the power and qubits in quantum computing systems increase, so does the need for cutting-edge capabilities to ascertain that they work. The Army Research Office and National Security Agency recently teamed up to solicit proposals for research that can help do exactly that.
The entities launched a broad agency announcement this week to boost the development of innovative techniques and protocols that allow for Quantum Characterization, Verification, and Validation, or QCVV, of intermediate-scale quantum systems. QCVV is essentially the science of quantifying how well a quantum computer can run quantum algorithms—and experts agree that it’s a necessary step towards useful quantum computing.

Quantum Teleportation Reported in a Qutrit For The First Time
Posted by Shailesh Prasad in categories: computing, quantum physics
Earlier this year, we celebrated a first in the field of quantum physics: scientists were able to ‘teleport’ a qutrit, or a piece of quantum information based on three states, opening up a whole host of new possibilities for quantum computing and communication.
Up until then, quantum teleportation had only been managed with qubits, albeit over impressively long distances. This proof-of-concept study suggests future quantum networks will be able to carry much more data and with less interference than we thought.
If you’re new to the idea of qutrits, first let’s take a step back. Simply put, the small data units we know as bits in classical computing can be in one of two states: a 0 or a 1. But in quantum computing, we have the qubit, which can be both a 0 and 1 at the same time (known as superposition).
