| 0:00.0 | This is Scientific American's 60 Second Science. |
| 0:05.0 | I'm Christopher Intagiyata. |
| 0:07.0 | Computers transmit information in bits, zeros and ones, off or on. |
| 0:12.0 | But in quantum computers, that off on logic becomes a little more flexible |
| 0:16.4 | because the bits in quantum computing called quantum bits or cubits can actually be zero |
| 0:21.9 | and one at the same time. Think of it like this. A coin |
| 0:25.8 | flipping through the air can be considered to be both heads and tails before it |
| 0:30.0 | lands. In that way it's like a cubit. Until you measure it, the cubit is zero and one. |
| 0:35.5 | Just as until the coin lands, it's both heads and tails. |
| 0:39.8 | But the quantum weirdness goes beyond simple cubits, because physicists have also created pairs of photons, particles of light, called quidits, with a d, for multiple dimensions. |
| 0:51.0 | And those dimensions are different colors of light. |
| 0:53.0 | So instead of being just zero and one, |
| 0:56.0 | like a regular quantum bit, these photon cutits |
| 0:59.0 | are, for example, simultaneously pink and purple and red and orange. In fact they can come in as many as |
| 1:04.8 | ten different colors which mathematically means ten different dimensions |
| 1:09.2 | compared to the two dimensions of a cubit. |
| 1:12.6 | Again, if that sounds crazy, just think of a ten-sided dye |
| 1:16.1 | spinning through the air instead of a two-sided coin. |
| 1:19.3 | It's all ten sides at once. |
| 1:21.7 | The study is in the journal Nature. The big advantage of quantum |
| 1:25.1 | bits and the point of developing them at all is they contain more information |
| 1:29.0 | than a classical bit, meaning quantum computers can use them in theory to solve super complicated equations much faster than a normal computer could and |
