[Abstract ] recent study physics at Yale University research team found that a “quantum cat” at the same time in a state between life and death, exist in two different places.

Tencent, according to foreign scientific
media reports, a “quantum cat” at the same time in a state between life and death, exist in two different places.
This is the latest study physics at Yale University research team based their experiments to establish the infamous Schrodinger cat paradox, combined with the concept of quantum entanglement.
The researchers found that they could induce a large number of photons to produce a match state, they said it will help promote speeding, reliable quantum computers.
Schrödinger’s cat is a thought experiment, by the Austrian physicist Erwin Schr & ouml; dinger invented in 1935.
In this hypothetical experiment, a cat is placed in a sealed box, close radioactive sample, Geiger counters and a bottle of poison.
observers do not know if the decay of atomic species has been, therefore, before the box is opened, the vial can not determine whether broken.
This means that the cat in a box in the living and dead commitments, until the box is opened to confirm that it is dead or alive.
In this new experiment, the researchers put this idea to the next level, that added an extra box in the program.
They set up a means of two three-dimensional microwave cavity and by the superconducting currents will join them together.
Then, one of the chambers of the photon is taken to a maze of doors, so that they produce a unique twist.
The researchers said that this produces two states, like imaginary cat, alive and dead in the state.
Chen Wang expressed cat big and clever.
It will not stay in a box, because the quantum state to be shared in the dual-chamber, and can not be described separately.
You can also take another point of view, there are two small and simple Schrodinger cat, were placed in two boxes, which are intertwined.
In the second chamber, the researchers found that the photon took a similar state.
They measure up to 80 photons’ cat size “, but also through the use of specialized control pulse can produce larger dimensions.
These findings suggest that scientists can manipulate complex quantum states and quantum coherence in a large range.
quantum computing can make the system reliable operation.
Superposition and entanglement to solve the problem, which is much faster than traditional computers.
However, there are still some problems.
The new experiment will be possible to address these challenges.
Co-author Robert Schoelkopf said, “cat” state is a very effective way to store redundant quantum information, quantum error correction.
Production in the two boxes cat just the first step in the error correction logic operation performed.
