If you go back just a bit further you find mercury delay-line memory, computer memory stored as analogue mercury waves.

I'm also not convinced it is correct to refer to quantum storage as "digital".

But yes,

The strangest storage device I encountered was the short lived magnetic bubble memory from intel. We had them in stock, but cannot tell whether they were ever sold. I guess they were way too expensive, floppys were cheap and the eeprom was promising. Ah, those were the days ...

No, you store entanglement states. It is certainly a new area of development. According to my informant:
There are two main types of quantum memory:

• Reservoir qubits: These are qubits that are stored in a special type of material called a quantum memory reservoir. The reservoir qubits are initially in a superposition of 0 and 1. When you want to store a piece of information, you can entangle the reservoir qubits with the qubits of the information you want to store. This will transfer the information to the reservoir qubits.
  
• Solid-state qubits: These are qubits that are stored in a solid-state material, such as a semiconductor or a superconductor. Solid-state qubits are more compact and scalable than reservoir qubits, but they are also more difficult to control.

But all this is waaaaay

Aaah, the good old days when one could revel in the sheer delight of watching the mercury flip, or dance to the tune of an FFT beating the drum.

There I go, channelling Bob's song again.
