The Mirror is, of course, entirely fictional. But the idea of an inanimate object having consciousness or even becoming sentient is no longer regarded as outrageous, especially within the realms of quantum mechanics and panpsychism. This concept forms the foundation of the Mirror in Furniture Sliders and the Bureau Archives Trilogy. Over time, its level of consciousness and sentience increases, and the dangers associated with it grow exponentially.
There are two elements of quantum mechanics that play into the story of the Mirror. The first is quantum entanglement, which posits that what happens in one place can affect what happens in another place instantaneously over any distance, including across the universe. It happens at a subatomic level. When two particles, such as a pair of 
photons or electrons, become entangled, they remain connected even when separated by vast distances.
A common misconception about entanglement is that the particles are communicating with each other faster than the speed of light, which would go against Einstein's special theory of relativity. Experiments have shown that this is not true, nor can quantum physics be used to send faster-than-light communications. Though scientists still debate how the seemingly bizarre phenomenon of entanglement arises, they know it is a real principle that passes test after test. In fact, while Einstein described entanglement as "spooky action at a distance", today's quantum scientists say there is nothing spooky about it.
While all of this is happening at an atomic and subatomic level, Furniture Sliders proposes that it is happening at a human level. Could a human be in two places at once, yet be interconnected in such a way that what happens to one incarnation happens to the other? And what happens when you have multiple incarnations?
This brings in the second element of quantum mechanics: superposition. The concept of quantum superposition might be difficult to understand or visualize. Many descriptions have been used to try to describe it. One is the analogy of a coin that is both heads up and tails up at the same time - a blended state where the coin is in multiple states until observed at which time it becomes one or the other. Another illustration is the famous .
Schrodinger's cat thought experiment, in which physicist Erwin Schrodinger imagined placing a cat in a sealed box along with a poisonous substance that has an equal chance of killing the cat - or not - within an hour. Schrodinger proposed that, at the end of the hour, the cat could be said to be both alive and dead, in a superposition of states, until the box is opened, and that the act of observation randomly determines whether the cat is alive or dead. Schrodinger intended this example to demonstrate what he saw as the absurdity of quantum science. But superposition is a major characteristic of quantum mechanics. In the quantum world, particles can exist in a superposition of multiple states simultaneously until they are observed or measured, at which point they "collapse" into one specific state.
When applied to the Mirror, the concept of superposition explains how the device manipulates time and reality in a way that seems impossible under normal conditions. The Mirror exploits the principles of superposition to create multiple potential timelines or temporal realities that exist in parallel, allowing it to influence or access multiple points in time without being constrained to a single path. The temporal slides that Sliders experience are influenced by superposition, where the Mirror creates multiple potential pathways in time for them to travel along. These temporal states are not fixed but exist as overlapping possibilities until the moment of the slide occurs. Sliders experience this as moving through layers of time, each one with its own set of events, people, and circumstances.
This explains the fluidity of time that sliders experience when using the Mirror - why sometimes events seem to shift unpredictably, or why the temporal landscape feels fragmented, as the Mirror weaves together different temporal threads before settling on a final one.
One of the most fascinating implications of applying superposition to the Mirror is the idea that it could access multiple realities at once. With superposition in play, the Mirror's function extends beyond simple temporal navigation. Instead of following a single, fixed timeline, the Mirror can manipulate a quantum field of time, where countless potential futures and past events exist in parallel. By using the principles of superposition, the Mirror can travel through this quantum time field, collapsing reality into a single path but with endless possibilities before it does so. The Mirror can calculate, adjust, and collapse multiple realities simultaneously, allowing it to manipulate time in a way that traditional technology cannot. The parallel realities and multiple possible futures that arise from this concept make the Mirror not just a time machine but a device capable of accessing and altering the quantum fabric of time, with far-reaching consequences for those who interact with it.
