Security professionals have said for years that the only way to make a computer truly secure is for it to not be connected to any other computers, a method called airgapping. Then, any attack would have to happen physically, with the attacker actually entering the room and accessing the computer that way, which is incredibly unlikely. In the case of computers containing highly sensitive information, additional, physical security can always be added in the form of security guards, cameras, and so on.

Researchers at Georgia Institute of Technology have uncovered a vulnerability in all computers, however, which can be exploited regardless of an air gap. It’s a vulnerability which you’d never suspect, and it’s one that’s hard to fight against. All CPUs emit electromagnetic signals when they are performing tasks, and the first thing these researchers discovered was that binary ones and zeroes emit different levels. The second thing they discovered is that electromagnetic radiation is also emitted by the voltage fluctuations and that it can be read from up to six meters away. These signals, by the way, are known as side-channels, and they are well-documented in the cryptography field.

So, ultimately, you would still have to be in the room to gain access.

For now, yes.
