How do you write a binary literal in ruby?

Most languages (Ruby included) allow number literals to be written in at least three bases: decimal, octal and hexadecimal. Numbers in decimal base is the usual thing and are written as (most) people naturally write numbers, 96 is written as `96`. Numbers prefixed by a zero are usually interpreted as octal based: 96 would be written as `0140`. Hexadecimal based numbers are usually prefixed by `0x`: 96 would be written as `0x60`. The question is: can I write numbers as binary literals in Ruby? How?
