To solve this prob­lem, researchers at Ghent Uni­ver­si­ty in Bel­gium built a com­put­er chip (mea­sur­ing just 5 mm in length) and then mapped all the imper­fec­tions in the chip as well as the sources of noise with­in it.

This enabled them to iden­ti­fy the ori­gin of the inter­fer­ence and mea­sure the quan­tum fluc­tu­a­tions with much greater sen­si­tiv­i­ty. The result: a chip capa­ble of gen­er­at­ing ran­dom num­bers 200 times faster than exist­ing com­mer­cial devices.
