Well nearly.
Scientists at the University of Rochester have invented a device that makes objects appear invisible over a range of angles.

The device uses lenses to have light pass around an object as though it isn't there, making the object seem invisible.
The phenomenon known as "cloaking", can be scaled up to nearly any size, so could be used to hide quite large objects, such as a young wizard.

Sadly the device requires a series of lenses and only works over a small angle range, so we're quite a long way off a proper invisibility cloak.
But we are one step closer.

John Howell, a professor of physics at the University of Rochester, has suggested many real life used for this technology such as letting a surgeon see through his hands, or a truck driver see his blind spots.
Or maybe to let a young boy wizard spy on his enemies...
