Beam-me-up money

The Transporter Problem

In Star Trek, the Transporter dematerializes crewmembers into energy patterns and reassembles them at destination. But quantum physics reveals an unsettling truth: quantum teleportation destroys the original quantum state while sending only information as classical data (ones and zeros), which is then reassembled elsewhere.

The crewmember who beams down is not the same one who beams back up.

How Banking Works Today

In traditional banking, money is “sent” by Bank A subtracting a number from its spreadsheet and sending a message to Bank B to add the same number to theirs. Only the message is sent—which is why we need banks to relay messages about our money.

Quantum Money: A New Paradigm

Quantum money represents value as the quantum state of a particle, exchanged via quantum teleportation. Unlike bank deposits (information about money) or Bitcoin (consensus records representing money), quantum money would be the money itself—an uncopyable particle that is the value.

As Fabrizio Genovese explains: “The most important thing to understand here is that quantum [money] behaves like a resource, not like data.”

The Advantages

Quantum money would be secured by unbreakable laws of superposition, entanglement, and the no-cloning theorem. It would offer:

• Self-custody: Keep qubits of money in hardware like physical cash in a pocket
• Permissionless exchange: No intermediary required
• Perfect privacy: No transaction ledger
• Instant transport: Like mailing physical cash, but instantaneous

Quantum vs. Blockchain

While Bitcoin enables peer-to-peer transactions over distance, blockchain transactions have limitations. As Gogioso notes: “Blockchain transactions are not quite peer-to-peer, because there’s always going to be part of the mechanism that can stop your transaction from going through. For economical, political, or technological reasons.”

Nothing will stop a quantum transaction.

The Timeline and Challenges

Quantum money faces one key limitation: it can only be transported to prepared hardware devices. Such devices don’t yet exist—Gogioso estimates we’re three to four years away from the earliest iteration.

The harder challenge may be establishing value acceptance. As Genovese says, getting security from quantum states is like getting energy from the Sun: “It’s what the universe gave us.” Building the transporter is one thing; getting others to accept qubits as payment is another.

When quantum money arrives, it will represent the safest conceivable way to send value—physics itself as the guarantor of security.
