Some researchers, such as Mika �����������Ա�ää, a physicist at Aalto University in Finland and a co-author of the second paper, wish to measure sensitive quantum effects but have been limited by the classical nature of their macroscopic measuring tools.

By bringing quantum effects into the macroscopic realm—or, put another way, returning classical objects to their true quantum selves—�����������Ա�ää hopes to investigate quantum gravity.

The new developments, while exciting, are “not for mobile phones,” �����������Ա�ää says dryly.

Mika �����������Ա�ää, a physicist at Aalto University in Finland and his colleagues took a different approach, manufacturing pairs of aluminum drum heads, or vibrating disks, about the width of a human hair onto a silicon chip.

“When we took the data, we had no idea if we were entangled or not,” �����������Ա�ää says.
