In a new teleportation landmark, researchers at Yale University have managed to teleport a quantum gate between qubits, whenever they wish.
The mechanism behind this intriguing phenomenon is quantum teleportation, a major trait of quantum mechanics that permits the transmission of unmeasured quantum states between two parties without sending the material state per se.
Starting from a base protocol first theorized almost three decades ago, researchers were able to prove the existence of the quantum gate without the of direct interaction. Quantum gates are needed in order to facilitate a system of quantum computation based several smaller networks of quantum systems, which may be prone to errors in the case of quantum computing CPUs.
A research team coordinated by lead researcher Robert Schoelkopf is now working on a more modular solution for quantum computing. Modularity has been already proved to be an effective solution for a variety of enterprises, from toys to space rockets, as it allows the building of powerful systems piece by piece. I a quantum architecture system, several modules containing processors would be linked together in order to create a larger network.
The modules are isolated in order to prevent possible interference, but at the same time it is harder to perform operations with isolated modules since their interactivity is decreased. The use of the teleport gates will allow isolated modules to interact with each other.
The demonstration marks a premiere in real-time communication as it the first time when it can take place in a reliable manner. Complete quantum computers may be able to reach speeds that would leave behind even the most modern supercomputers, with significantly smaller sizes and power consumption. Yale researchers are hard at work, already developing quantum computers that use superconductors.
Qubits, the essential parts of quantum calculations are prone to be faulty, and the research hopes to stabilize and improve their quality. It remains to be seen if the dream will become true in the future.
Laura grew up in a small town in northern Quebec. She studied chemistry in college, graduated, and married her husband one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children. Laura is an advocate for people with disabilities.
