Primeiro Bit programme

The Primeiro Bit question

Could a system record and make accessible a message chosen at a later time? The programme proposes studying this question through the role of the sender, the physical mechanism and the receiving infrastructure.

The programme's hypotheses

Infrastructure at the destination

Certain mechanisms might require receiving conditions to be established in advance. A device that merely reads a message must be distinguished from a structure that contributes to the physical possibility of the channel.

Information as the initial objective

The proposal is to investigate minimal communication before requiring the transport of objects or organisms. This is a research priority, not an inevitable sequence of discoveries demonstrated by the programme.

Improving the receiver

If a working channel could transmit useful instructions, these messages might help improve the channel itself. The hypothesis depends on capacity, reliability, local resources and causal consistency, which still need to be studied.

The three-paper plan

1. 01

   Quantum foundations and receiving infrastructure

   A critical review of models, their differences, signalling limits and requirements for responsible research.

   Planned manuscript
2. 02

   The seed-receiver model

   Conditions for an initial system to receive information useful for improving its own infrastructure.

   Planned manuscript
3. 03

   Feasibility and verification criteria

   How to distinguish communication from coincidence, leakage, prediction or retrospective interpretation.

What the literature offers

Ji, Lloyd and Wilde analyse limits on communication from the future to the past within a mathematical model involving closed timelike curves and post-selection. The study does not present a constructed temporal receiver. [1]

Established quantum teleportation uses a shared quantum resource and classical communication. This protocol does not, by itself, amount to receiving a message sent from the future. [2]

These references provide background for review. They are neither endorsements of Link to Future by their authors nor evidence proving the Primeiro Bit hypotheses.

Safety and governance

Before any experimental proposal, the programme must specify the mechanism being considered, its resources and possible failures. Planetary risk or safety is not estimated from an abstract receiver concept.

Instructions supposedly arriving from the future would also require verification. A message's claimed origin does not guarantee the accuracy of its content or the safety of its application.

Primeiro Bit retains its own identity. Institutional support from Link to Future is an intended relationship that has yet to be formalised.
